Consider the statements about force on current cariying conductor : 1. It was given by Alexandra Volta. 2. It is determined by Fleming Left hand Rule. Choose the correct option from the codes given

Options

A. only 1
B. only 2
C. both 1 and 2
D. neither 1 and 2

Answer

b

Explanation

An electric current flowing through a conductor produces a magnetic field. The field so produced exerts a force on a magnet placed in the vicinity of the conductor. French scientist Andre Marie Ampere (1775-1836) suggested that the magnet must also exert an equal and opposite force on the current-canying conductor. The direction of the current and that of the magnetic field are perpendicular to each other and the force is per-pendicular to both of them. The three directions can be illustrated through a simple rule, called Fleming’s left-hand rule.
