What is the relationship between electricity and magnetism?

   Electromagnetism

Explanation:  Electricity is one of the forms of energy that is transmitted, i.e. it flows through conductors, and is used for different purposes. Electricity is generated by the movement of charged particles, electrons and protons, directed motion, and thus the electric current is transmitted. In order for particles to move, that is, flow through the conductor, they need to be stimulated by a change in the charge, anything that drives electrons and protons. Otherwise, electrons and protons, even when they are at rest, have electricity that is in balance, that is called static electricity.  So some change in charge from the outside causes their movement and this is an electric current.

From the outside, magnetism is a force that can be attractive or repulsive at a certain distance. This distance to which this repulsive or attractive force acts is called a magnetic field. Magnetism also arises, also from the electric charge of the electron, other particles can be, but mainly of the electron. It is known that the electrons are an integral part of the atomic coil, i.e. they revolve around the nucleus, but they also rotate or spins around their own axis. The spinning of the electrons causes a magnetic field. The higher the number of electrons that spin in one particular direction, the stronger the magnetic field. The direction of electron spins determines the direction of the magnetic field.

Electricity and magnetism are two interconnected forces, and their relationship is electromagnetism. This means that when an electrical current flows through a conductor, it induces a magnetic field, which can be registered, for example, by registering the moving of a compass needle. Also, the magnetic field can induce electrical current in the conductor.

Sample Response:

Electrical and magnetic fields occur together. A change in current induces a magnetic field. A change in magnetic field induces a current.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
