In what direction is the force of an electron if that electron is moving east through a magnetic field that points north?

A charge moves in a circle in a magnetic field at 12 m/s. If the 2 x10−5 T fieldpoints out of the page and the circle is clockwise with a radius of 5 cm, is the chargepositive or negative?If the absolute value of the charge is 3 C, find the magnitude of the force pushing on it.

A magnetic dipole is under the influence of two magnetic fields. The angle between the field directions is 60°, and one of the fields has a magnitude of 1.2 × 10-2 T. If the dipole comes to stable equilibrium at an angle of 15° with this field, what is the magnitude of the other field?

The charges moving inside a conductor experience a magnetic force if the conductor is placed in a magnetic field, resulting in a potential deference called Hall Voltage. If the direction of B (into the plane of the paper) and / (towards up) are as shown in the figure, In which face of the conductor does the electron tend to accumulate due to this effect.  a) Face 1 b) Face 2 c) Face 3 d) Face 4
