Moving Charges ...

A charged particle is moving in a magnetic field of strength B perpendicular to the direction of the field. if q and m denote the charge and mass of the particle respectively, then the frequency of rotation of the particle is

A charge particle of mass m and charge q enters a region of uniform magnetic field B perpendicular of its velocity v. The particle initially at rest was accelerated by a potential difference V (volts) before it entered the region of magnetic field. What is the diameter of the circular path followed by the charged particle in the region of magnetic field ?

An electron having mass (9.1 × 10^-31 kg) and charge (1.6 × 10^-19 C) moves in a circular path of radius 0.5 m with a velocity 106 m s ^-1 in

A thin flexible wire of length L is connected to two adjacent fixed points and carries a current I in the clockwise direction, as shown in the figure. When the system is put in a uniform magnetic field of strength B going into the plane of the paper, the wire takes the shape of a circle. The tension in the wire is

An electron is moving in an orbit of radius R with a time period T as shown in the figure. The magnetic moment produced may be given by

The resultant force on the current loop PQRS due to a long current carrying conductor will be

Three long, straight parallel wires, carrying current, are arranged as shown in figure. The force experienced by a 25 cm length of wire C is

The figure shows three situations when an electron with velocity v travels through a uniform magnetic field B. In each case, what is the direction of magnetic force on the electron?

A and B are two conductors carrying a current I in the same direction, x and y are two electron beams moving in the same direction.
