In an electric field a charge (Q) experiences a force F = QE. If charge is positive then force is directed in the direction of field whereas if charge is negative force acts on it in the opposite direction of field.
Magnetism - Basic concepts: 1. Pole strength: The ability of a pole of a magnet to attract or repel another magnetic pole is called its pole strength. Units : A-m 2.

Q. What is ionisation potential energy? For hydrogen atom the energy necessary to remove an electron from first orbit to its outermost orbit (n=∞) is 13.6-0 = 13.6eV. This ene
Magnetic monopole A hypothetical particle that sinks of the magnetic field & constitutes sources. Magnetic monopoles have never been determined, but would cause fairly minor m
Factors on which Magnetic Force Depends: The magnetic force depends on following factors: 1. Nature of Pole: Like poles repel each other and unlike pole attract each other.
The current induced in the conductor due change in magnetic field is called eddy current.we study more about this in electro magnetic laws.
