Magnetic force on a straight wire carrying current placed in a magnetic field
In the previous topic we have seen about Lorentz force, now let us study some of the applications related to magnetic force.
1) Magnetic force on a straight current-carrying wire placed in a magnetic field.

| Straight wire kept in Magnetic Field |
Consider a straight wire of length L as shown in the figure below. Let q be the charge due to current I flowing through the conductor and B be the magnetic field in which the wire is kept. As long as the current flows, the electron moves with a drift velocity Vd. Thus the magnetic force according to Lorentz law acting on this wire is given by,
