Do the magnetic reactions which cause aurora borealis affect earths rotation like an electric motor?
No, the magnetic reactions that cause aurora borealis do not affect Earth's rotation like an electric motor. The aurora is a result of solar wind interacting with Earth's magnetic field, creating light displays in the polar regions. Earth's rotation is primarily influenced by gravitational forces, not by magnetic reactions.
What else can I help you with?
How are magnets and motors related?
They both produce magnetic fields. So when together they attract.
What are 2 main reasons for the earths magnetic field?
The main reasons for the Earth's magnetic field are the movement of molten iron in the outer core and the Earth's rotation. The flow of molten iron generates electric currents that produce the magnetic field, while the planet's rotation helps maintain the field's strength and orientation.
In this electric motor an electric current causes the coil to rotate changing?
In this electric motor, an electric current flowing through the coil interacts with the magnetic field, generating a force that causes the coil to rotate. This rotation changes the direction of the magnetic field around the coil, which in turn causes the coil to keep rotating in the same direction.
What is the speed of rotation of the magnetic field called?
The speed of rotation of the magnetic field is called magnetic flux. It is a measure of the flow of a magnetic field through a particular area.
The operation of an electric motor depends on?
The operation of an electric motor depends on the interaction of magnetic fields, passing of electric current through coils of wire (armature), and the resulting electromagnetic forces that cause the motor to rotate. The direction of the current and the arrangement of the magnetic fields determine the direction of the rotation, while the flow of current and the strength of the magnetic fields dictate the speed and torque of the motor.
Which device works by rotation a wire coil within a magnetic field to produce electric current?
generator

Which device works by rotating awire coil within a magnetic field to produce electric?
An electric generator works by rotating a wire coil within a magnetic field to produce electricity. This rotation induces a current in the wire coil, which can then be harnessed and used to power electrical devices.
What is jupiters magnetic field caused by?
Jupiter's magnetic field is caused by the convection of liquid metallic hydrogen in its outer core. This creates electric currents that produce the magnetic field. Jupiter's rapid rotation also plays a role in generating its strong magnetic field.
How does an electric motor rotate once it's electromagnet is aligned along the magnet field or it's permanent magnet?
Once the electromagnet in an electric motor is aligned along the magnetic field produced by permanent magnets, a torque is generated due to the interaction of magnetic fields. This torque causes the rotor (part of the motor that holds the electromagnet) to rotate. The rotation continues as the electromagnet switches polarity to stay aligned with the changing magnetic fields, creating a continuous rotation.
What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
Is it true that magnetic poles are defined by earths rotation?
No, it is not true. The magnetic poles may be influenced by Earth's rotation, but they are certainly not defined by it.
Magnet that spins on its axle in a motor?
The rotation of the magnet within a motor generates a changing magnetic field, inducing an electric current in nearby wire coils according to Faraday's law of electromagnetic induction. This current creates a magnetic field that interacts with the rotating magnet, causing torque that drives the motor's rotation. By continuously alternating the direction of the current flow, the magnet's spins are synchronized with the changing magnetic fields to maintain rotation.
