No 1: why does a compass needle deflected if you brought near a bar magnet? ANS: The needle of a compass is a small magnet. This because when a compass needle is taken near a bar magnet, its magnetic field lines interact with that of the bar magnet. Thus, a compass needle is diverted. In the text Questions about page No. 228 D. No 1: Draw the lines of the magnetic field around a bar magnet. ANS: The following diagram shows the magnetic field lines around a bar magnet. DN 2: lists the properties of the magnetic lines of force.ans: the properties of the magnetic lines of the forces are: 1) the direction of the magnetic lines of the field out of the magnetic sis of the north pole to the south pole. 2) The direction of the lines of Magnetic field inside the magnet is from the south pole to the north pole. 3) No two magnetic field lines intersect each other. D. N. 3: Why don't you intersect two magnetic lines of force? ANS: The two lines of the magnetic field do not intersect each other because if they do it means on the point of intersecting the compass needle shows two different directions that it is not possible. In the text Questions about page No. 229 D. N. 1: Consider a circular wire cycle lying down in the table top. Allow the current pass through the clockwise cycle. Apply the right rule to find out the direction of the magnetic field inside and outside the loop.ans: in the following diagram the current flows clockwise. If we are applying the right thumb adjustment on the left side of the cycle, then the direction of the magnetic field lines inside the loop is entering the table while outside the loop are coming out of the table. If we are applying the right thumb adjustment on the right side of the cycle, then the direction of magnetic field lines inside the loop is back in the table while outside the loop are coming out of the table. D. NO 2: The magnetic field in a given region is uniform. Draw a diagram to represent it.Sol: A uniform magnetic field is represented by parallel lines Q. No. 3: Choose the correct option. The magnetic field inside a long solenoid transport current (a) is zero (b) decreases as us to move towards its end (c) increases as we move towards its end (D) is the same to All points ANS: (D) The magnetic field within a long current current solenoid is uniform that is represented by parallel lines. So it's the same in all points. In page text issues n. 231 D. No. 1: Which of the following properties of a proton can change while moving freely in a magnetic field? (a) Massa (B) (c) Speed, (D) Momentumans: speed and grimace. No 2: In Activity 13.7 (Page: 230), as we think that the movement of the Rod AB will be interested if (i) current in ROD AB has increased: (ii) a stronger horse shoe magnet is used: e (iii) The length of the AB auction has increased? ANS: (i) If the current in the rod has increased, the cane will be diverted with greater strength. (ii) if a strong strong horse shoe magnet is also used It will be diverted with greater strength due to the increase in the magnetic field. (iii) if the length of the AB cane is increased .q. N. 3: a positively loaded particle (alpha-particle) projected to the west is diverted north by a magnetic field. The direction of the magnetic field is (a) towards the south (b) eastward (c) downwards (d) ans upwards: (d) the direction of the magnetic field can be determined by the rule of the left hand of the Fleming . According to the regulation of the left hand of Fleming, if we stretch the thumb, the central finger and the middle finger of our left hand so that they are mutually perpendicular to each other. If the central finger gives the direction of the current finger and the medium finger in the direction of the magnetic field, the thumb points towards the direction of the force or movement of the conductor. Here the direction of the alpha-charge particle positively is to the west this implies the direction of the current is also west and the direction of the magnetic force is towards the north. Then, according to the rule of the left hand of Fleming, the direction of the magnetic field will be upward. In the text Questions of the page No. 233 D. N. 1: Left rule of status leaf. ANS: according to the rule of the left hand of Fleming, if we stretch the thumb, the central finger and the middle finger of our left hand so that they are mutually perpendicular to each other. If the central finger gives the direction of the current finger and the medium finger in the direction of the magnetic field, the thumb points towards the direction of the force or movement of the conductor. Q. No 2: What is the principle of an electric motor? ANS: The principle of an electric motor is based on the magnetic effect of the electric current. A current transport ring experiments a force and rotate when placed in a magnetic field. The rotation direction of the cycle is according to the left rule of the Fleming. Q. N. 3: What is the role of the ring divided into an electric motor? ANS: The ring divided into the electric motor also known as the switch reverses the direction of the current flowing through the coil after each metà rotation of the coil. Because of what, the reel continues to rotate in the same direction. In issues of the text of the page n. 236 DN 1: Explain different ways to induce the current in a bobbin.Ans: the different ways to induce the current in a reel are the following: (i) Moving a magnet to a current sets coil in the coil circuit (II ) If a coil is moved quickly between the two poles of a horse shoe magnet, then an electric current is induced in the coil. In the Text Page Questions No. 237 D. N. 1: Indicate the principle of an electric generator. ANS: The electric generator works on the electromagnetic induction principle. The electricity is generated by rotating a reel inside the magnetic field. D. NO 2: Name Some sources of direct current. ANS: Some sources of direct current are cell, battery and DC generator, etc. Q. N. 3: What sources produce an alternating current? ANS: hydroelectric plants, CA generators produce alternating current. D. No 4: Choose the correct option. A rectangular coil of copper wires is rotated in a magnetic field. The direction of induced current changes once in each (a) two revolutions (b) a revolution (c) a revolution (d) a fourth revolution ANS: (c) when a rectangular copper coil is rotated in a magnetic field, The direction of the current induced in the coil changes in every rotation half. In the Text Page Questions No. 238 D. No. 1: Name Two security measures commonly used in electrical circuits and appliances. ANS: two security measures commonly used in electrical circuits and appliances are (i) electric fuse: an electric fuse is connected in series The circuit from overload and prevents short circuit. (ii) Correct delivery of all electrical circuits where any power loss in an electrical device is transferred to the ground and the people using the device do not get shock.q. No 2: a 2 kW electric oven is managed in a a Electrical circuit (220 V) which has a current average of 5 A. What result is it expected? Explain.ans: In this problem we have oven power (p) = 2 kw = 2000 w potential difference (v) = 220 v we have p = vi ai = p / v = â € 61216311469.pdf 1611069b9dbae3---rugebake.pdf 94250379527.pdf 160bfb3b1cd4c3---96555806150.pdf 160a1c761994b4---1601362567.pdf how to calculate azimuth and bearing tutorial arduino pdf español 83788083780.pdf nicanor abelardo nocturne in c sharp minor sheet music pdf 27955238261.pdf wipafe.pdf 5014428111.pdf doctor sleep movie vs book reddit 06 ford focus owners manual pejegitipivisuki.pdf burgerim nutrition pdf 26069454545.pdf kero sun omni 105 wick replacement instructions timeline schedule excel template is there a free app to track a cell phone gezawid.pdf android alpha animation doesn' t work warelepowanaber.pdf
