When is induced electromotive force produced in a coil placed near a magnet?
An induced electromotive force is produced in a coil placed near a magnet when there is a relative motion between the coil and the magnetic field. This motion causes a change in the magnetic flux passing through the coil, leading to the generation of an electromotive force according to Faraday's law of electromagnetic induction.
How does a magnet pulling a car demonstrate the principles of magnetic force and motion?
When a magnet pulls a car, it demonstrates the principles of magnetic force and motion by showing how the magnetic force between the magnet and the car causes the car to move towards the magnet. This is because the magnet creates a magnetic field that exerts a force on the car, resulting in motion.
What Motors contain electromagnets that transform?
Electric motors contain electromagnets that transform electrical energy into mechanical energy to generate motion. These electromagnets interact with a permanent magnet to create a rotating force that drives the motor.
Why don't we feel the earth moving and rotating despite its constant motion?
We don't feel the Earth moving and rotating because its motion is constant and we are moving along with it at the same speed. Our bodies have adapted to this motion over time, so we don't perceive it as movement.
How do you power a fan with magnets?
To power a fan with magnets, you can use a magnetically coupled rotating system where the motion of one magnet induces motion in another magnet connected to the fan. This setup can create a magnetic field that drives the rotation of the fan blades. However, this method typically requires precise engineering and isn't commonly used for everyday fan applications due to efficiency and practicality issues.

What transfers motion to generator?
A rotating shaft
Which mechanical motion including rotating parts can create a mechanical hazard that could grab your clothing or hair and pull you into the danger area?
rotating motion

How is a motor different from a generator and how is a generator different then a mot or?
A motor takes electricity and creates rotating motion. A generator takes rotating motion and turns it into electricity.
Is earth rotating on its axis the longest motion?
yes
Is it false that a strong magnet will cause a larger change in motion than a weak magnet?
No, that statement is false. The strength of a magnet affects the magnetic field it generates but not necessarily the change in motion it causes. The change in motion is determined by factors such as mass, distance, and the magnetic field's influence on an object.
How do you change energy of motion into electrical energy?
A rotating machine like a generator requires first a permanent magnet of sort. The magnet can be a natural source or induced by an electric current flow. A copper wire as it cuts cuts trough a magnetic field it self induce a current flow. Therefore current will flow into an external load.
Why is angular momentum used?
In the same way that objects in linear motion tend to remain that way, objects which are rotating tend to keep rotating. Thus, we need both linear and angular (rotational) motion.
What is a stator magnet?
A stator magnet is a permanent magnet located on the stationary part of an electric motor or generator. It produces a magnetic field that interacts with the rotating part (rotor) to generate mechanical motion or electrical power. Stator magnets play a crucial role in converting electrical energy into mechanical or vice versa in various applications.
