9. iF THE LOop is in the xy plane and the current direction is
not known, the magnetic field can be in -z or +z direction ( from
right hand corkscrew rule)
Now magnetic force ona moving charge is q v x B. So the force i 0
only if B is parallel to v
hence, any particle moving along z = 0 will not experience any
force ( as its parallel to z axis)
so, E. x = 0, z = 0

A circular loop of wire, centered at the origin, lies in the xy plane. The loop has a radius of 10.0cm. A cylindrical magnet (radius 0.5 cm and length-5 cm) starts out at rest with its primary axis along the z-axis. The bottom tip of the magnet is a north-pole and is situated at z 8 cm. The magnet is dropped straight down so that it falls north- pole down and it goes straight through the center of the loop....

A circular loop of wire with area A lies in the xy-plane. As viewed along the z-axis looking in the −z-direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B⃗ is given by τ⃗ =D(3i^−3j^), where D is a positive constant, and for this orientation of the loop the magnetic potential energy U=−μ⃗ ⋅B⃗ is negative. The magnitude of the magnetic field is B0=15D/IA. Determine the component Bx of B⃗...
