Magnetism and Electromagnetism Out of the following statements, concerning an electric field, which statement is not true?

The electric field intensity at a point is numerically equal to the force exerted upon a charge placed at that point
The electric intensity is a vector quantity
Unit field intensity in the exertion of a force of one newton on a charge of one coulomb
An electric field is defined as a point in space at which an electric charge would experience a force

Magnetism and Electromagnetism When a magnet is in motion relative to a coil the induced e.m.f. does not depend upon

Motion of the magnet
Pole strength of the magnet
Number of turns of the coil
Resistance of the coil

Magnetism and Electromagnetism The left hand rule correlates to

Current, magnetic field and direction of force on a conductor
Magnetic field, electric field and direction of force on a conductor
Self induction, mutual induction and direction of force on a conductor
Current, induced e.m.f. and direction of force on a conductor

Magnetism and Electromagnetism Strength of an electromagnet can be increased by

Increasing current supply
All of the listed here
Increasing the cross-sectional area
Increasing the number of turns

Magnetism and Electromagnetism In a simple magnetic field the strength of magnet flux

increases continuously from initial value to final value
decreases continuously from initial value to final value
first increases and then decreases till it becomes zero
is constant and has same value in energy part of the magnetic field
