What type of energy is magnetic field?

Answer 1

Magnetic energy is the energy stored in a magnetic field in the form magnetic field lines.

Power Transformers used in electricity supply send energy from one coil to another, at a different voltage, via the magnetic field.

Answer 2

Electromagnetic energy can be "defined" as:

EME = hf= zC^2f = zCI=CV= WbI=VWb/z.

Electromagnetic energy is a hybrid word indicating a hybrid theory, electricity and magnetism. The essence of this hybridism is the "world view" of the scientist. Is there a preferred world view? Should we have electric energy or magnetic energy only?

The essence of the world view differences goes back to space and time. Science has a sense of space and a sense of time. Man had an early sense of space and the stars including the sun. Later man developed a sense of time. By the time of Newton space and time were co-equals in science. With the coming of Electromagnetism and Maxwell's Equations, time and space became coupled by the speed of light. Finally Einstein joined them in his concept of a four dimensional universe, spacetime.

The idea of spacetime maintains the hybridism inherent in electromagnetism. I prefer a non-hybrid concept of space, where space is a four dimensional, quaternion concept., Maxwell's Equations and electromagnetism are all about space not time and the Universe is electric. Given an electric field, E= Er + Ev, is a quaternion electric field with Er the real field and Ev the vector field, Maxwell's Equations are given by the first space derivative of the electric field. This is a Boundary condition or Continuity Condition.

0= (d/dr + Del)E= (dEr/dr - Del.Ev) + (dEv/dr + DelxEv + Del Er)

This gives two equations

0 = dEr/dr - Del.Ev

and

0= dEv/dr + Del Er

DelxEv =0 indicates that the other two vectors are parallel or anti-parallel and the vector equation sums to zero.

The radial distance is a real scalar r=ct and dr=cdt introduces time into the equations.

Magnetism is introduced by E=Bc thus dE/dr= dE/cdt= dB/dt. Introducing time introduces the magnetic field. The time variation of the magnetic field is just the distance variation of the electric field.

The relation E=Bc was discovered by Maxwell and Weber. Weber considered it a coincidence. Maxwell considered it evidence that light was electricity! Maxwell's prediction that light was electricity is still one of the greatest scientific achievements.

Quaternions are yet to be appreciated in science and spacetime hybridism continues.

Answer 3

Magnetism is not an energy in itself. Magnets have a force, and if that force is used to move an object over a certain distance, the energy is called work. If energy is used to hold an object attracted or repelled by the magnet from moving, then there is potential energy stored in the held object/magnet system.

Answer 4

Magnetic energy is an energy field that surrounds a magnet. Magnets contain north and south poles which produce lines of force from north pole to south pole.

Answer 5

Magnetic power is property of materials that respond at an atomic or subatomic level to an applied magnetic field.

Answer 6

Electromagnetic radiation produced in magnetic and electric fields. These fields are filled with electrically charged particles.

Answer 7
