A steady current I flows through a long cylindrical wire of radius a. Find the magnetic field B inside and outside the cylinder if the current is: a) Uniformly distributed on the outer surface of the wire. b) Distributed in a way that the current density J = k * r (k is a constant and r is a distance from the axis).
A long straight, solid metal wire of radius $2 \mathrm{~mm}$ carries a current uniformly distributed over its circular cross-section. The magnetic field induction at a distance $2 \mathrm{~mm}$ from its axis is $B$. Then, the magnetic field induction at distance $1 \mathrm{~mm}$ from axis will be (a) $B$ (b) $B_{1} 2$ (c) $2 \underline{B}$ (d) $B$
Magnetic Effect of Current
Round 1
A conducting circular loop of radius $r$ carries a constant current $I$. It is placed in a uniform magnetic field $B$ such that $B_{0}$ is perpendicular to the plane of the loop. The magnetic force acting on the loop is: (a) $\operatorname{Ir} B_{0}$ (b) $2 \pi \operatorname{lr} B_{0}$ (c) $\pi I r B_{0}$ (d) zero
