Question

state the rule used to find the direction of force on a charge moving perpendicular to magnetic field​

Answer 1

Answer:

Explanation:

Image result for state the rule used to find the direction of force on a charge moving perpendicular to magnetic field​

The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the right hand point in the direction of v, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.

Answer 2

Answer:

The Fleming's left-hand rule gives the direction of force experienced by current carrying conductor placed in an external magnetic field.

Fleming's left hand rule:

When an electric current passes through a straight wire, an external magnetic field is applied across that flow, the wire experiences a force perpendicular both to the field and to the direction of the current flow. The Fleming's left hand rule can be used to determine the direction of the force, magnetic field and current. A left hand can be held, so that the thumb, first finger and second finger are held mutually perpendicular to each other. The thumb represents the direction of Motion resulting from the force on the conductor. The first finger represents the direction of the magnetic Field. The second finger represents the direction of the Current.
