Define magnetic flux and state Faraday's law, describing the relationship between the magnetic flux linked through a circuit and the current induced in the circuit. What is the force on a straight wire of length l carrying a current I in the presence of a magnetic field B ? Two long frictionless and resistanceless parallel rails, separated by a distance a, are connected by a resistanceless wire. A magnetic field B is oriented perpendicular to the plane containing the two rails. A frictionless conduction slider of resistance R and mass m is placed perpendicular to the rails and is given an initial velocity u along the rails. Obtain an expression for the force F on the slider while it moves at velocity v. Hence, find the maximum distance that the slider travels?

Solution:
