The number density of free electrons in a copper conductor is estimated as 8.5xx10^(28)m^(-3) . How long does an electron take to drift from one end of a wire 3.0m long to its other end? The area of cross-section of the wire is 2.0xx 10^(-6)m^(2) and it is carrying a current of 3.0A.

A closely wound solenoid of 2000 turns and area of cross-section 1.6 xx 10^(-4)m^(2)? carrying a current of 4.0 A. is suspended through its centre allowing it to turn in a horizontal plane. (a) What is the magnetic moment associated with the solenoid? (b) What is the force and torque on the solenoid if a uniform horizontal magnetic field of 7.5 xx 10^(-2)T is set up at an angle of 30^@ with the axis of the solenoid?

Write the expression for magnetic dipole moment due to a current loop.
