A square of side $2.0\,m$ is placed in a uniform magnetic field $B = 2.0\, T$ in a direction perpendicular to the plane of the square inwards. Equal current, $i = 3.0\, A$ is flowing in the direction shown in figure. Find the magnitude of magnetic force on the loop

Two free parallel wires carrying currents in opposite direction

Two long straight wires $P$ and $Q$ carrying equal current $10\,A$ each were kept parallel to each other at $5\,cm$ distance. Magnitude of magnetic force experienced by $10\,cm$ length of wire $P$ is $F_1$. If distance between wires is halved and currents on them are doubled, force $F_2$ on $10\,cm$ length of wire $P$ will be :

Two straight parallel wires, both carrying $10$ $ampere$ in the same direction attract each other with a force of $1 \times {10^{ - 3}}\,N$. If both currents are doubled, the force of attraction will be

A circular current loop of radius a is placed in a radial field $B$ as shown. The net force acting on the loop is

A square loop $ABCD$, carrying a current $i,$ is placed near and coplanar with a long straight conductor $XY$ carrying a current $I,$ the net force on the loop will be
