What are magnetic fields and how do they shape the Universe?

magnetic field  As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion The spinning and orbiting of the nucleus of an atom produces a Magnetic Field Produced by a Current-Carrying Circular Loop B=μ0I2R B = μ 0 I 2 R , where R is the radius of the

All magnetic objects produce invisible lines of force that extend between the poles of the object Earth is similar to a giant bar magnet with magnetic field The electric field is actually the force per unit charge experienced by a non moving point charge at any given location within the field, whereas the magnetic
