The relationship between electricity and magnetism ask for a detailed explanation, and more points

Relationship between electricity and magnetism:

When an electric current passes through a conductor, a magnetic field (the space around the magnet with magnetic forces) is generated around the conductor, that is, electromagnetism.

When a conductor cuts a magnetic field line or the magnetic field line passing through the coil changes, an induced electromotive force or induced current is generated in the conductor or coil, which is called "magnetic electricity".

Electricity and magnetism are actually two sides of the same thing.

Many major electrical equipment such as transformers, generators, electric motors, etc., are made according to the principle of electromagnetic induction.

Electricity to magnetic, electric motors.

Magnetic to electrical, electromagnetic induction.

An electric field is a type of field, like a force field, a magnetic field.

Perpetual motion machines do not exist because of the law of conservation of energy, and there is a loss of energy.

There is an electric field around the charge;

There is a magnetic field around the current and a voltage around the magnetic current (a changing current).

Oster's experiments illustrate that energized conductors can produce magnetic effects.

The phenomenon of electromagnetic induction creates generators.

The principle of magnetism generates electricity to create an electric motor (electrical energy – mechanical energy).

Electromagnetic induction phenomenon: a part of the conductor in the magnetic field moves by cutting magnetic inductance lines.

1. Electromagnetism: There is a magnetic field around the current. Application: electromagnet, electromagnetic relay, electric bell, etc.;

2. Magnetism, that is, the phenomenon of electromagnetic induction: electric current can be obtained by using a magnetic field. Application: Generator;

3. The magnetic field has a strong effect on the energized conductor. Application: Electric motor.

Maxwell's theory: A changing magnetic field produces an electric field, and a changing electric field produces a magnetic field.

Maxwell's Research:

There is a magnetic field around the moving charge.

An electric field is present around a moving magnetic field.

A perpetual motion machine is a device that emits energy without consuming it.

The magnetic field is generated by the directional motion of the charge, and the induced current is caused by the changing magnetic field, which simply means: "the changing electricity produces magnetism, and the changing magnetism produces electricity", and the changing electric field and the changing magnetic field together constitute an inseparable electromagnetic field. The relationship between electricity and magnetism is that they excite each other and occur at the same time, which is often called electromagnetic waves.

Electromagnetic waves can be divided into radio waves, infrared rays, visible light, ultraviolet rays, X-rays, Y-rays, cosmic rays, etc.

The magnetic field is generated by the excitation of an electric current, and there is a magnetic field around the current, and the directional motion of the charge forms an electric current, so the moving charge can also excite the magnetic field.

The essence of the induced current is the change of the magnetic field, to be precise, the change of magnetic flux produces the current electricity and magnetism can be converted into each other, the changed magnetic field produces the induced current, and the current can excite the magnetic field.

The right-hand rule determines the direction of the magnetic field, the magnetic inductance line.

is a closed curve.

When an electric current passes through the conductor, a magnetic field is generated around the conductor (the space around the magnet is dyed by magnetic force), that is, "electromagnetism". When a conductor cuts a magnetic field line or the magnetic field line passing through the coil changes, an induced electromotive force or induced current is generated in the conductor or coil, which is called "magnetic electricity".

There is a magnetic field around the current, as evidenced by the Danish Oster.

The energized solenoid is judged by the pole, and the ampere of the cong cave extends the right hand.

The four fingers follow the current, and the direction of rotation cannot be reversed.

The thumb is the n pole, and the palm cut is marked as the s.

Electromagnetic induction Faraday, magnetic generation of electricity to close the circuit.

Some conductors cut magnetic wires, and there are induced current lines.

The direction changes to alternating current, and the mechanical energy is converted into electrical energy.

When an electric current passes through a conductor, a magnetic field (the space around the magnet with magnetic force) is generated around the conductor, which is called "electromagnetism". When a conductor cuts a magnetic field line or a magnetic field line passing through a coil changes or changes, an induced electromotive force or induced current will be generated in the conductor or coil, that is, "magnetic electricity".

The memory mantra of electromagnetism has a magnetic field around the electric current, as evidenced by the Danish Oster.

The energized solenoid is judged by the pole, and the ampere rule is extended to the right hand.

The four fingers follow the current, and the direction of rotation cannot be reversed.

The thumb is the n pole, and the palm cut is marked as the s.

The memory formula of magnetism and electricity is electromagnetic induction Faraday, and the magnetism and electricity must be closed.

Part of the conductor cut socks collapsed magnetic wires, induced current lines in them.
