A steady current `i` flows in a small square lopp of wire of side `L` in a horizontal plane. The loop is now folded about its middle such that half of it lies in a vertical plane. Let `vecmu_(1)` and `vecmu_(2)` respectively denote the magnetic moments due to the current loop before and after folding. Then

A

`vec(mu_(2))=0`

B

`vec(mu_(1))` and `vec(mu_(2)` are in the same direction

C

`(|vec(mu_(1))|)/(|vec(mu_(2))|)=sqrt(2)`

D

`(|vec(mu_(1))|)/(|vec(mu_(1))|)=(1/(sqrt(2)))`

A straight wire and a circular loop both carrying currents are in the same vertical plane. There is no contact between the two at the point A. If B_(1) and B_(2) are magnetic fields due to i_(1)andi_(2) respectively at the point C, the centre of the loop, then the total field at C is:

A current carrying circular loop lies on a smooth horizontal plane. Can a uniform magnetic field be set up in such a manner that the loop turns around itself (i.e., turns about the vertical axis).

Two infinite long straight parallel wires A and B are separted by 0.1m distance and carry equal currents in opposite directions. A square loop of wire C of side 0.1m lies in the plane of A and B. The loop of wire C is kept parallel to both A and B at a distance of 0.1m from the nearest wire. Calculate the EMF induced in the loop C while the currents in A and B are increasing at the rate of 10^(3) A//s . Also indicate the direction of current in the loop C.

In Fig ABCDEFA was a square loop of side l, but is folded in two equal parts so that half of it lies in the x-z plane and the other half lies in the y-z plane. The origin O is centre of the frame also. The loop carries current 'i'. The magnetic field at the centre is

(ii) In figure., this loop is placed in a horizontal plane near a long straight conductor carrying a steady current I_1 at a distance l as shown. Give reasons to explain that the loop will experience a net force but no torque. Write the expression for this force acting on the loop.

A square loop ABCD of side 'a' carrying current I is folded about an axis passing through its centre ( y -axis). The two halves are inclined at angle 30^(@) with xy plane as shown. Find the magnetic field at origin. The origin coincides with the centre of loop.

A steady current is flowing in a circular coil of radius R, made up of a thin conducting wire. The magnetic field at the centre of the loop is B_L . Now, a circular loop of radius R//n is made from the same wire without changing its length, by unfounding and refolding the loop, and the same current is passed through it. If new magnetic field at the centre of the coil is B_C , then the ratio B_L//B_C is
