358602 Shown in the figure is a circular loop of radius \({r}\) and resistance \({R}\). A variable magnetic field of induction \({B=B_{0} e^{-t}}\) is established inside the coil. If the key \({(K)}\) is closed, the electrical power developed right after closing the switch is equal to

358603 Assertion :
An induced emf is generated when magnet is withdrawn from the solenoid.
Reason :
The relative motion between magnet and solenoid induces \(emf.\)

358604 A conducting ring of radius \(r\) is placed perpendicularly inside a time varying magnetic field given by \(B=B_{0}+\alpha t\), as shown in the figure. \(B_{o}\) and \(\alpha\) are positive constants. Find the emf produced in the ring.

358605 A 800 turn coil of effective area \(0.05\;\,{m^2}\) is kept perpendicular to a magnetic field \(5 \times {10^{ - 5}}\,\;T\). When the plane of the coil is rotated by \(90^{\circ}\) around any of its coplanar axis in \(0.1\;s\), the emf induced in the coil will be:

358606 The four separate figures below involve a cylindrical magnet and a tiny light bulb connected to the ends of a loop of copper wire. These figures are to be used in the following question. The plane of the wire loop is perpendicular to the reference axis. The states of motion of the magnet and of the loop of wire indicated in the diagram, Speed will be represented by \(v\) and CCW represents counter clockwise.
