∙ 15y agoThe strength of an Electro-Magnet can be increased by 1.Increasing the number of turns of wire winded around it. 2.Increasing the amount of current passing through it. Magnetic Field = Relative Permeability (Mu not) * n( no. of turns) * I (Current passing through)

What kind of magnet can vary its strength and polarity?
Electromagnet
What will increase the strength of a copper electromagnet?
One way to increase the strength of a copper electromagnet is by adding another coil. Another way is by wrapping the copper coil around a nail made of iron.Adding more loops to the wireWrapping the copper wire around an iron nailIncreasing the current
Is it true that The strength of an electromagnet is easy to control?
yes it is easily controlled.
What effect does decreasing the number of coils around the nail have on the strength of the electromagnet?
Decreasing the number of coils reduces the strength of the magnet.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
What happens to the strength of magnetic force in an electromagnet when increasing the current through the coil?
The strength is increased, this is how Roller Coasters operate.
How does the strength of an electromagnet with an iron core compare to an electromagnet that simply has air at its core?
Permeability of the medium, that too, if it is ferro-magnetic material then it gets increased to a larger extent and so the magnetic induction too increases enormously.
What has a wire-wrapped core?
A coil of wire or a coil in the shape of a cylinder is a typical shape for an electromagnet (or a solenoid). The strength of the magnetic field of an electromagnet can be increased significantly if the coil is wrapped around an iron core. This configuration may be called an inductor when used as an element of an electrical circuit.
What does not affect the strength of an electromagnet?
a donut
Does not affect the strength of an electromagnet?
a donut
Does freezing an electromagnet affect the strength of it?
yes
What factors control the strength of an electromagnet?
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.
What are the advantages and disadvantage's of an electromagnet?
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
What kind of magnet can vary its strength and polarity?
Electromagnet
What kind of magnet can vary its strength polarity?
an electromagnet
What type of magnet can vary its strength and polarity?
electromagnet
What can affect the strength of an electromagnet?
The power of the battery controlling it.
