When the direction of current flow is reversed the current of an electromagnet swap over?
When the direction of current flow is reversed in an electromagnet, the magnetic poles also reverse. This means that the north pole becomes the south pole and vice versa. So, the current in the electromagnet determines the polarity of the magnetic field it produces.
How do make an electromagnet stop working?
To make an electromagnet stop working, you can disconnect the power source supplying electricity to the electromagnet. This will interrupt the flow of current through the coil of wire, which is necessary to generate the magnetic field. Alternatively, you can reverse the direction of the current flow by connecting the wires in a different way, which will cancel out the magnetic field.
How can a polarity of an electromagnet be determined if the direction of current flow is known?
The polarity of an electromagnet can be determined by the right-hand rule. If the direction of the current flow is known, curl your right hand fingers in the direction of the current flow. Your thumb points in the direction of the north pole of 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.
The what of an electromagnet is determined by the direction of current flow?
The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.
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.
When the direction of current flow is reversed the current of an electromagnet swap over?
When the direction of current flow is reversed in an electromagnet, the magnetic poles also reverse. This means that the north pole becomes the south pole and vice versa. So, the current in the electromagnet determines the polarity of the magnetic field it produces.

In an electromagnet the wires get hot due to the flow of what?
Electric current
The what of an electromagnet is determined by the direction of current flow?
The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.
Voltage is pressure and current is flow what opposes flow?
Reverse current.
How can electromagnets be controlled?
Electromagnets can be controlled by adjusting the amount of current flowing through the wire coils. Increasing the current strengthens the magnetic field, while decreasing the current weakens it. Alternatively, changing the direction of the current flow can reverse the polarity of the electromagnet.
How can the polarity of an electromagnet be determined if the direction of current flow is unknown?
The polarity of an electromagnet can be determined using the right-hand rule: wrap your fingers around the coil in the direction of the current flow (conventional current flow is from positive to negative), with your thumb pointing in the direction of the magnetic field. The side of the coil where your thumb points is the north pole of the electromagnet.
How does turning off the current in a industrial electromagnet affect its magnetic field?
Turning off the current in an industrial electromagnet will cause the magnetic field to weaken and eventually disappear. This is because the magnetic field is created by the flow of current through the coils of the electromagnet, so stopping the current flow stops the generation of the magnetic field.
What happens when you remove the power source from an electromagnet?
When you remove the power source from an electromagnet, the magnetic field that was being generated by the flow of electric current through the coils of the electromagnet dissipates. As a result, the electromagnet loses its magnetic properties and no longer attracts or repels magnetic materials.
