A cube is placed so that one corner is at the origin and three edges are along x, y, and z axes of a coordinate system . Use vectors to compute a. The angle between the edges along

The magnetic field in a region is given by → B = B 0 ( x a ) ^ k . A square loop of side d is placed with its edges along the x and y axes. The loop is moved with a constant velocity → v = v 0 ^ i. The emf induced in the loop is :

The magnetic field existing in a region is given by vector B = B0(1 + x/l)vector k. A square loop of edge I and carrying a current i, is placed with its edges parallel to the X-Y axes. Find the magnitude of the net magnetic force experienced by the loop.

A body constrained to move along the z-axis of a coordinate system is subjected to a constant force given by F = -i + 2j + 3 k N, where i, j, k are unit vectors along the x-, y-, and z axes
