What happens to the electromagnet when the circuit is closed?

An electromagnet if formed by pushing current through a coil. If the circuit is truly open, current will cease to flow, thus no electromagnet.


What happens if you increase the current in an electomagnet?

As current increases, the electromagnet strength will increase.


What happens when you reverse the current in a current-carrying magnetic field?

The polarity of the electromagnet reverses.


What is the relationship between current and force in an electromagnet?

The relationship between current and force in an electromagnet is direct and proportional. Increasing the current flowing through the electromagnet coil will result in a stronger magnetic field being produced, leading to a greater force exerted by the electromagnet. Conversely, reducing the current will weaken the magnetic field and decrease the force.


What happens when you reverse the current in an electromagnet?

The magnetic field reverses direction.


What happens if you reverse the current flow in an electromagnet?

Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.


How can you change the strenght of an electromagnet?

You can change the strength of an electromagnet by increasing or decreasing the amount of current flowing through the wire coils. More current will increase the magnetic field strength, while less current will decrease it. Additionally, using a different material for the core of the electromagnet can also affect its strength.


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.


What happens as you increasse and decrease the number of loops in an electromagnet?

Increasing the number of loops in an electromagnet strengthens the magnetic field produced, resulting in a stronger electromagnet. Conversely, decreasing the number of loops weakens the magnetic field, making the electromagnet less strong.


What happens when the electrical current stops in an electromagnet?

When the electrical current stops in an electromagnet, the magnetic field produced by the coil will dissipate, causing the magnetism to disappear. The electromagnet will no longer attract or repel other magnetic materials until current is passed through the coil again.


What happens when the base current of a transistor is decrease?

in a properly biased transistor, collector and emitter current also decrease
