The field strength of an electromagnet (and the shape of that field) will largely be determined by the physical characteristics and geometry of the coil (wire size, number of turns, spacing of turns, diameter of coil, etc.), the current flow through the coil's wire and the material and shape of the core. The most variable aspect of the electromagnet is the current we run through it. Once the electromagnet is designed and constructed, the limits are "built in" and about all we can vary is current. Use the link to the GSU Hyperphysics site and it's diagram of an electromagnet. (Be sure to scroll down a bit.) Also, look around on that site, if you have time. There is a lot of good basic physics there. The explanations are very reader friendly and the diagrams are pretty good, too.
What else can I help you with?
What happens if you reverse the current flow in an electromagnet?
Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.
What happens when you turn on the current in an electromagnet?
When you turn on the current in an electromagnet, it induces a magnetic field around the magnet. This magnetic field allows the electromagnet to attract or repel other magnetic objects or influence nearby currents. The strength of the magnetic field can be adjusted by changing the amount of current flowing through the electromagnet.
What happens when a current stops flowing through the wire of an electromagnet?
magnetic fieldOnly
What happens when the electrical current stops in an electromagnet?
When the electrical current stops in an electromagnet, the magnetic field produced by the coil will dissipate, causing the magnetism to disappear. The electromagnet will no longer attract or repel other magnetic materials until current is passed through the coil again.
In an electromagnet why is changed by flipping the direction of the electrons which is controlled by the commutator?
Changing the direction of the current in the electromagnet by flipping the direction of the electrons through the commutator changes the direction of the magnetic field generated by the electromagnet. This is because the magnetic field produced by a current-carrying wire is directly related to the direction of the current flow. By reversing the current direction, the polarity of the magnetic field is also reversed, which allows for control over the attractive or repulsive forces exerted by the electromagnet.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
What happens to the electromagnet when the circuit is closed?
An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What happens when you reverse the current in an electromagnet?
The magnetic field reverses direction.
What happens if you reverse the current flow in an electromagnet?
Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.

When you turn on the current in an electromagnet, it induces a magnetic field around the magnet. This magnetic field allows the electromagnet to attract or repel other magnetic objects or influence nearby currents. The strength of the magnetic field can be adjusted by changing the amount of current flowing through the electromagnet.

What happen when you change the direction of current in an electromagnet?
If you change the direction of current in an electromagnet, (which by the way is just a coil of wire) then the direction of the magnetic field will also be reversed: That is to say, what was north is now south. If you want more info. look up "the left hand rule".
What happens when a part of electromagnet is disconnected?
When a part of an electromagnet is disconnected, the magnetic field strength of the electromagnet decreases significantly, as the current passing through the coil is interrupted. This leads to a weakening or loss of magnetism in the electromagnet, which may affect its ability to attract or repel magnetic materials.
