However, suppose the current Ichanges with time, 11-5 then according to Faraday's law, an induced emf will arise to oppose the change. glasses are polarized. The gravitational potential energy of the coconut when it starts to fall is 560J What is the magnitude of the magnetic field B The coil rotates at 75.7 rad/s in a 0.219-T magnetic field. Problem 1. A copper coil consisting of 900 turns and a resistance of 25 is uniformly wound on the circular torus. What is the magnitude of the magnetic field B at the centre of the coil? At the start, the normal to the coil is perpendicular to the magnetic field. 1 See answer When a meteor enters the Earth's atmosphere, three forces act on the meteor. The radius of the coil is 0.025 m. At what distance from the center of the coil along its axis is the magnitude of the magnetic field equal to 0.48 T? Polo Sport Jumper Vintage, (a) A circular coil of 30 turns and radius 8.0 c m.Carrying a current of 6.0 A is suspended vertically in a uniform horizontal magnetic field of magnitude 1.0 T.The field lines make an angle of 60 with the normal to the coil.
