The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.
What 3 factors affect the strength of a magnetic force?
The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. Magnetism is the force by which objects are attracted to or repelled by other objects.
Which factors affect the strength of an electromagnet quizlet?
Factors that affect the strength of an electromagnet are current, strength of magnetic material, and conductivity of electric metal. Changing the amount of current flowing through the electromagnet will also change the field it produces.
What factor has the greatest effect on the strength of an electromagnet?
The magnetic field is caused by the current flowing in the wire. The bigger the current the stronger the magnetic field and hence the stronger the electromagnet.
How can you increase the strength of an electromagnet?
You can make an electromagnet stronger by doing these things:
- wrapping the coil around a piece of iron (such as an iron nail)
- adding more turns to the coil.
- increasing the current flowing through the coil.
How does distance affect the strength of an electromagnet?
If the distance between two magnets with like poles gets smaller, then the repelling force between them will get bigger, because the force between two magnets gets stronger as they get closer together, and weaker as they get farther apart.
Which electromagnet is the strongest?
The strongest continuous manmade magnetic field, 45 T, was produced by a hybrid device, consisting of a Bitter magnet inside a superconducting magnet. The resistive magnet produces 33.5 T and the superconducting coil produces the remaining 11.5 T.
What is the effect on the strength of the electromagnet when the number of battery is increased?
The current is a big factor in the strength of the magnetic field. As the number of batteries increases, the current increases. So, as the number of batteries increases, so does the strength of the electromagnet.
What factors determine the strength and size of the magnetic force between objects?
The magnitude of the magnetic force between them depends on how much charge is in how much motion in each of the two objects and how far apart they are. The direction of the force depends on the relative directions of motion of the charge in each case.
