(C) The force $F$ experienced by a current-carrying conductor in a magnetic field is given by the formula: $F = B I L \sin \theta$. Given: Current $I = 3\, A$,Length $L = 40\, cm = 0.4\, m$,Magnetic field $B = 500\, G = 500 \times 10^{-4}\, T = 0.05\, T$,Angle $\theta = 30^\circ$. Substituting the values: $F = (0.05) \times 3 \times 0.4 \times \sin(30^\circ)$ $F = 0.05 \times 3 \times 0.4 \times 0.5$ $F = 0.03\, N = 3 \times 10^{-2}\, N$.

Force on a Current Carrying Conductor

$A$ rectangular loop carrying a current $i$ is situated near a long straight wire such that the wire is parallel to one of the sides of the loop and is in the plane of the loop. If a steady current $i$ is established in the wire as shown in the figure,the loop will

$A$ semi-circular current-carrying wire having radius $R$ is placed in the $x-y$ plane with its centre at the origin $O$. $A$ non-uniform magnetic field $\vec B = \frac{B_o x}{2R} \hat k$ (where $B_o$ is a positive constant) exists in the region. The magnetic force acting on the semi-circular wire will be along:
