What else can I help you with?
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.
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.
Why magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
How do the size of the current in the coil affect the strength of a electromagnet?
The strength of an electromagnet is directly proportional to the current flowing through the coil. Increasing the current in the coil increases the magnetic field strength produced by the electromagnet. This means that increasing the size of the current in the coil will make the electromagnet stronger.
What must pass through a coil in order to make an electromagnet?
An electrical current will cause an electromagnet to energise.
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.
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.
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.
How can you make a electromagnet lose its magnetism?
by decreasing its current,by decreasing turns of coil
How do you make an electromagnet stronger or weaker?
To make an electromagnet stronger, increase the number of turns in the coil, use a stronger magnetic core material, and increase the current flowing through the coil. To make it weaker, decrease the number of turns in the coil, use a weaker magnetic core material, or reduce the current flowing through the coil.
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 type of magnet is a electromagnet?
An electromagnet is a type of temporary magnet that is created by passing an electric current through a coil of wire wrapped around a magnetic core, such as iron or steel. The strength of an electromagnet can be adjusted by changing the amount of electric current flowing through the coil.
