If an electron enters a magnetic field with its velocity pointing in the same direction as themagnetic field, then -. If is rotated about its vertical diameter through 1 8 0 m in 0. A circular coil consisting of 500 turns with an area of 6.0x10-4 m 2 is rotating in a uniform magnetic field. A circular coil consisting of 500 turns with an area of 6.0x10-4 m2 is rotating in a uniform magnetic field. A circular coil of 500 turns of wire has an enclosed area of 0.1m 2 per turn.It is kept perpendicular to a magnetic induction of 0.2 T and rotated by 180 o about a diameter perpendicular to the field in 0.1 second. If the total mass of. It is kept perpendicular to a magnetic field of induction 0.2 Tand rotated by 180oabout a diameter perpendicular to the field in 0.1 sec. A proton and an alpha particle of the same velocity enter in a uniform magnetic field which is acting perpendicular to their direction of motion. A 500-turn circular coil with an area of 0.050 0 m2 is mounted on a rotating frame, which turns at a rate of 20.0 rad/s in the . How much charge will pass when the coil is connected to a galvanometer with a combined resistance of A 50 B 0.4 C C 0.2 C D 4 C Medium A Circular coil of wire consisting of 100 turns, each of radius 8.0cm carries a current of 0.40A. What is the magnitude of the magnetic field B at the centre of the coil? Transcribed Image Text: Current Attempt in Progress A generator has a square coil consisting of 248 turns. Using the coordinate system indicated (with the z axis out of the page), state the direction of the magnetic field at points A and B. The gravitational potential energy of the coconut when it starts to fall is 560J A hollow air cored inductor coil consists of 500 turns of copper wire which produces a magnetic flux of 10mWb when passing a DC current of 10 amps. Using the formula for the magnetic field at the center of a current carrying a circular coil, where0= 4 10-7Wb/Am, N is the number of turns, I is the current intensity and r is the radius of the coil, \(B = 10^{-7} \frac{2\pi 500 0.30}{0.06}\), AAI ATC Junior Executive 25 March 2021 Official Paper (Shift 1), Copyright 2014-2022 Testbook Edu Solutions Pvt.
