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.
In an electromagnet the magnetic forces increase as this increase?
In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
What happens to the strength of an electromagnetic field when you increase the current flowing through the coil of wire around an iron bar?
Increasing the current flowing through the coil of wire around an iron bar will increase the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
What must happen for an electromagnet to have a magnetic field?
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
Is an electromagnet a coil of wire with current flowing through?
Yes.
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.
Why magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
In an electromagnet the magnetic forces increase as this increase?
In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
What happens to the strength of an electromagnetic field when you increase the current flowing through the coil of wire around an iron bar?
Increasing the current flowing through the coil of wire around an iron bar will increase the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
An electromagnet its magnetism if the electric current stops flowing?

How can you make a electromagnet lose its magnetism?
by decreasing its current,by decreasing turns of coil
What must happen for an electromagnet to have a magnetic field?
An electromagnet must have a current flowing through its coil of wire in order to generate a magnetic field. When an electric current passes through the coil, it creates a magnetic field around the electromagnet.
What type of magnet is created when electric current flows through a coil wire?
An electromagnet is created when electric current flows through a coil of wire. This coil acts as a magnet when current is passed through it, allowing it to attract magnetic materials and exert a magnetic field. The strength of the electromagnet can be controlled by adjusting the amount of current flowing through the coil.
Which magnet made by an electric current flowing through wires?
An electromagnet is made by an electric current flowing through wires. The magnetic field is created when the current passes through the wire, generating a magnetic field around it. This magnetic field can attract or repel other magnetic objects nearby.
How does increasing the voltage of a supply in a electromagnet affect the strength of the magnetic field?
Increasing the voltage of a supply in an electromagnet increases the current flowing through the coil, which in turn increases the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.
