Consider a long, straight conductor carrying a constant current I0. Coplanar with it, an isosceles triangular conducting loop is kept as shown:Then, consider the following statements and choose the correct option(s):Mutual inductance of the system isμ0b2πh[(a+h)ln(a+ha)−h]Mutual inductance of the system is μ0h4πa[(a+h)ln(a+ha)−h]If current is switched off, triangular loop moves leftwardsIf current is switched off, triangular loop moves rightwards

The loop of wire is being moved to the right at constant velocity. A constant current I flows in the long straight wire in the direction shown. The current induced in the loop isSelect one:a.clockwise and proportional to I2b.counterclockwise and proportional to I2.c.counterclockwise and proportional to I.d.zero.e.clockwise and proportional to I.

A current carrying closed loop in the form of a right angle isosceles triangle ABC is placed in a uniform magnetic field acting along AB. If the magnetic force on the arm BC is Fthe force on the arm AC is A testbook B C

A square loop of side a, mass m and resistance R is placed coplanar with a long fixed wire carrying current I as shown. The current in the conductor is suddenly switched off. Neglecting gravity, the velocity acquired by the loop will be:

Two circular loops, one of small radius r and other of larger radius R, such thatR >> r, are placed coaxially with centres coinciding. Obtain the mutual inductance ofthe arrangement.
