A rectangular loop in the xy-plane carrying a current I lies in a uniform Magnetic field B = axBx + ayBy + azBz. Determine the Force and the torque on the loop

A circular coil traveled by current through has a magnetic dipole moment of magnitude 1.23 A ⋅ m2 . What is the maximum magnitude of the torque that the coil, carrying this current, can experience in a uniform 45.6 mT magnetic field.

In the figure, two circular arcs have radii a = 13.3 cm and b = 11.5 cm, subtend angle 0 = 77.0°, carry current i = 0.345 A, and share the same center of curvature P. What are the (a) magnitude and (b) direction (into or out of the page) of the net magnetic field at P? P

The figure below shows a long conducting coaxial cable and gives its radii (R₁ = 4.78cm, R₂-6.5cm, R3-16cm). The inner cable has a uniform current density of J = 5.1 A/m², and the outer cable carries a uniform current I = 2.1A flowing in opposite direction. Assume that the currents in each wire is uniformly distributed over its cross section. Determine the magnitude of the magnetic field in terms of po at a distance r = 12.5cm from the center of the cable. Express your answer using four decimal places. R2 R3 I
