Magnetism is the phenomenon that arises from the force between objects that produce A magnetic field exerts a force on particles in the field due and the strength of the magnetic field The field is increasing or decreasing all the time he says We know this from studies of the paleomagnetic record Earth s present day magnetic field is in fact much stronger than normal The dipole moment a measure of the intensity of the magnetic field is now 8 x amps x m2 That s twice the million year average of 4 x amps

Reference Magnetic Field Unit Magnetic field strength is defined by vector field which has a direction and a magnitude or strength The number of magnetic flux lines which go through the unit area perpendicular to magnetic field is called Flux density BThe magnitude of the magnetic force on a charge moving at a speed in a magnetic field of strength is given by where is the angle between the directions of and This force is often called the Lorentz force

Horizontal Intensity of Earth’s magnetic field Elements of Geomagnetism Horizontal and vertical components of the earth’s magnetic intensity The force acting on a unit pole strength of north pole at any place of the earth due to geomagnetism is called the geomagnetic field intensity or total intensityMagnetic Field Strength H The magnetic fields generated by currents and calculated from Ampere s Law or the Biot Savart Law are characterized by the magnetic field B measured in Tesla The unit for the magnetic field strength H can be derived from its relationship to the magnetic field B B=μH

The main difference between magnetic field and magnetic flux is that magnetic field is a region where magnetic poles and moving charges experience a force Sometimes the term magnetic field may be also used to refer to the quantity magnetic field strength Magnetic field strength symbol H is defined as the magnetomotive force per unit length of a magnetic circuit As magnetomotive force is the product of the current flowing through a winding and
