magnetic fieldOnly
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 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 the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
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 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.

An electromagnet is only live (magnetised) when a current is flowing through the coil.

by decreasing its current,by decreasing turns of coil
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.
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.
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.
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.
