# The Concept of Electromagnetic Field and Fleming’s Left hand rule

An electromagnetic field is that field that results from the interaction of the electric and magnetic fields.

When a current carrying conductor is passed in a magnetic field, the conductor will experience a force.

To identify the directions of the force (motion), current and field, Fleming’s Left Hand Rule is employed.

## Fleming’s Left Hand Rule

It states that, “If the first three fingers are mutually at right angles to each other, with the Forefinger in the direction of the field, B and the mIddle finger in the direction of the convectional  current, I, then, the thuMb is in the direction of the motion, M or force on the conductor”.

Fleming’s Left Hand Rule is for current-carrying conductor, used to determine the direction of  current in a conductor. The rule can only be used if the magnetic field and current are  perpendicular or inclined to each other but not when they are parallel.
