Four wires each of length `2.0` meters area bent into four loops `P,Q,R` and `S` and then suspended into uniform magnetic field. Same current is passed in each loop. Which statement is correct?

Three wires each of length 2*0m are bent into different rectangular loops and then suspended in a magnetic field, figure. If the current in each of them be the same, which loop shall be acted upon by largest torque? If any of the wires be bent into circular loop, then?

A wire of length l is formed into a circular loop of one turn only and is suspended in a magnetic field B. When a current i is passed through the loop, the maximum torque experienced by it is

Two wires of equal lengths are bent in the form of two loops. One of the loops is square shaped whereas the other loop is circular. These are suspended in a uniform magnetic field and the same current is passed through them. Which loop will experience greater torque? Give reasons.

A wire of length L is bent to form a circular loop of number of turns n. The coil is placed in a magnetic field of induction B and a current is passed through the coil. What will be the maximum torque acting on the coil?

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 :

One of the two identical conducting wires of length L is bent in the form of a circular loop and the other one into a circular coil of N identical turns. If the same current passed in both, the ratio of the magnetic field at the central of the loop (B_(L)) to that at the central of the coil (B_(C)) , i.e. (B_(L))/(B_(C)) will be :

A wire of length l carries a steady current. It is bent first to form a circular plane loop of one turn. The magnetic field at the centre of the loop is B. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field at the centre caused by the same is
