There are two current carrying planar coils made each from identical wires of length L. `C_1` is the circular (radius R) and `C_2` is square (side a). They are so constructed that they have same frequency of oscillation when they are placed in the same uniform `vecB` and carry the same current i. Find a in terms of R.

There are two current carrying plannar coils made each from identical wires of length L. C_1 is circular (radius R) and C_2 is square (side a). They are so constructed that they have the same frequency of oscillation when they are placed in the same uniform magnetic field vecB and carry the same current. Find a in terms of R.

Two wires of same length are shaped into a square and a circle. If they carry same current, ratio of the magnetic moment is

Two wires of same length are shaped into a square and a circle. If they carry same current, ratio of the magnetic moment is

Two wires of same length are shaped into a square and a circle. If they carry same current, ratio of the magnetic moment is

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 :
