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?

Four wires each of length 2.0 metres are 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

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.
