How do you use a sentence about electromagnets with an iron bar and copper coil?
The student tested his theory using electromagnets, an iron bar, and a piece of copper coil.
What effect would increasing the number of loops in a coil have on an electromagnet?
Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.
Why a coil of wire with a direct current passing through it will magnetise a piece of iron?
The coil would act as if a bar magnet inserted along its axis. So any iron material inserted gets magnetised.
Does coil of wire with current passing through it magnetise a piece of iron?
yes it does the current flows in a wire it creates a magnetic field around the wire.
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.

What is turned inside a coil of wire to generate electricity?
soft iron
What c is the piece of iron inside a magnet?
core
What affects how strong an electromagnet is?
The number of turns in the coil of wire, the electrical current flowing through the coil, and the presence of an iron core inside the coil.
What c is the piece of iron inside an electro magnet?
Core

When a current-carrying wire is made to form a coil around a piece of iron the device is called?
A solenoid with iron core also known as electromagnet
Can Cooper be used as a magnet?
When copper is used as a wire to build a coil with a lot of whorls and a piece of iron is inserted in the hole of the coil this is called an electromagnetic device since that a voltage is applied in the coil, thus generating an electromagnetic power which is similar to that natural magnetic iron.
The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
How can you turn a piece of iron into a magnet?
To turn a piece of iron into a temporary magnet, wind a coil of (insulated) copper wire around it and run a DC current through the wire. The iron will become the core an electromagnet -- the one you just constructed. As long as direct current flows through the coil, the iron core will attract ferromagnetic materials.jkghyjy Wrap many coils of lacquered copper wire round an iron nail. When electricity is sent through the coils, the nail becomes magnetised. The iron is an electromagnet as long as the power is on. When a piece of iron is brought near the magnet it also becomes a temporary magnet.
Why is a soft iron core used in a relay coil?
because it can magnetize and demagnetize easily
