A strong electromagnet produces a uniform magnetic field of 1.60 T over a cross-sectional area of 0.200 m2. A coil having 200 turns and a total resistance of 20.0 2 is placed around the electromagnet. The current in the electromagnet is then smoothly reduced until it reaches zero in 20.0 ms. What is the current induced in the coil?

Expert Solution
Introduction:
  • As per Faraday's law whenever a conductor is placed inside a varying magnetic field the magnetic field will interact with the conductor to produce an electromotive force. This process is known as electromagnetic induction.

 

  • The emf generated is given by,

ε=Ndϕdt

Here N is the number of turns in the coil and dϕdt is the change in magnetic flux.
