The intensity of the magnetic field (measured in Teslas) produced by an electromagnet is directly proportional to the current (measured in Amperes) passing through it's coil windings. Therefore, as long as other variables remain constant, one can vary the intensity of the magnetic field by varying the current. Specifically, the intensity of the magnetic field will vary by the same factor as the current, so if the current is halved, the intensity of the magnetic field will also be halved; and if the current is tripled, the intensity of the magnetic field will also be tripled.

How does an eletromagnet work?
The eletromagnet works by the energy flowing through the wire wrapped around the iron rod that causes the magnetic field
Does a magnetic field strengthen on weekend as you move away from the eletromagnet?
The magnetic field becomes weaker as you move away from the electromagnetic source.
Is the direction of electron beams in a CRT is controlled by electric field?
Practically speaking electron beam is controlled by magnetic field produced by passing electric current through yoke coil.
Is an electromagnet what is changed by flipping the direction of the electrons which is controlled by the commutaor?
In an electromagnet, flipping the direction of electrons changes the magnetic field, which is controlled by the commutator.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.

What does electromagnets do?
It is the joining of electricity and magnetic field, it is the study if the interaction between the two.
Region around a magnet in which magnetic force can act?
Magnetic freild
Does Eris have a magnetic field?
no. Eris does not have a magnetic field
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
