At some point, not close to its ends, within a solenoid of arbitrary length, calculate the approximate magnetic field if the solenoid carries a current of 18.0 A and has 17.0 turns/m of the solenoid’s length. Also, if the number of turns per m is tripled, the magnetic field will change in what way?
A square conducting loop is in a region of uniform, constant magnetic field. Can the loop be rotated about an axis along one side and no emf be induced in the loop? Discuss, in terms of the orientation of the rotation axis relative to the magnetic-field direction.
A flexible circular loop of radius 10 cm lies in a magnetic field of 4 T. It is oriented so that itsplane makes an angle of 30o to the magnetic field lines. Compute the magnitude of the inducede.m.f. in the loop, if the radius of the loop changes to 20 cm from 0.20 s to 0.50 s
