Acircular loop of wire with a radius of 12.0 cm and oriented in the horizontal xy-plane is located in a region of uniform magnetic field. a field of 1.6 t is directed along the positive z-direction, which is upward. a) if the loop is removed from the field region in a time interval of 2.8 ms, find the average emf that will be induced in the wire loop during the extraction process. e =? ? b)if the coil is viewed looking down on it from above, is the induced current in the loop clockwise or counterclockwise?

25.85081 V

Explanation:

= Magnetic flux

t = Time taken = 2.8 ms

B_i = Initial magnetic field

B_f = Final magnetic field

r = Radius of loop = 12 cm

A = Area =

Induced emf is given by (Faraday's law)

The average emf that will be induced in the wire loop during the extraction process is 25.85081 V

Here the average emf induced is pointed toward z direction. If viewed from above then the direction of the current will be counter clockwise.

the body's situation won't change the forces are equal opposit and on the same body
