What is the value of the current in a wire of 10cm long at the right angle to a uniform magnetic field of 0.5 Weber/m2 when the force acting on the wire is 5N?
When a particle of charge q and mass m enters into a uniform magnetic field B moving with a velocity v perpendicular to the direction for the field it describes a circular path of radius
When a particle of charge q and mass m enters the uniform magnetic field B moving with velocity v perpendicular to the direction of the field the time required by a charged particle to make a complete revolution in a magnetic field is given by
