Question

A force exerted on the current carring conductor the direction of this force depends on both the direction of the current and the direction of the magnetic field this force is maximum when the direction of current is perpendicularity to the direction of the field
A)by which law we can determine of force exerted on the current carrying conductor

Answer 1

Fleming's LEFT HAND RULE

Answer 2

Fleming's left hand rule explain that whenever a current carrying conductor is placed in the magnetic field it experience a force and this force is perpendicular to both the magnetic field B and the direction of current I.

Hope u get the point!
