A triangular loop (ABC) having current i_(2) and an infinite wire having current i_(1) are placed in the same plane.Find the magnetic force of interaction between the infinite wire and the loop ABC .
A rectangular loop of wire with dimensions shown in figure is coplanar with a long wier carrying current 'I' . The distance between the wire and the left side of the loop is r . The loop is pulled to the right as indicated. What are the directions of the induced current in the loop and the magnetic forces on the left and right sides of the loop when the loop is pulled ?
A fixed straight wire is near a movable square loop as shown in the figure below. In which direction is the square loop supposed to move?
The magnetic field at O due to current in the infinite wire forming a loop as a shown in Fig.
A square current carrying loop is suspended in a unifrom magnetic field acting in the palne of the loop. If the force on one arm of the loop is vec(F) , the net force on the remaining three arms of the loop is
A long straight wire is coplanar with a current carrying circular loop of radius R as shown in Fig. Current flowing through wire and the loop is I_0 and I, respectively. If distance between centre of loop and wire is r=2R, calculate force of attraction between the wire and the loop.
Two identical wires each of length L are bent to form a circular loop and a square loop. If the same current i flows in the two wires, then the ratio of the magnetic inductions at the centre of the circular and square loops is :
