A strong electromagnet produces a uniform
field of 1.31 T over a cross-sectional area of
0.195 m2. A coil having 245 turns with a total
resistance of 16
is placed around the electro-
magnet, and the current in the electromagnet
is turned off, reaching zero in 19.3 ms.
What current is induced in the coil?
Answer in units of A.
