When a magnet is used in a motor, it interacts with the electrical current flowing through the coils of wire, resulting in the generation of a magnetic field. This interaction creates a force that causes the motor to move, converting electrical energy into mechanical energy. The magnet provides a magnetic field that helps drive the motor's motion.
What else can I help you with?
Which pair is made up of two things that work in opposite way's A bar magnet and horseshoe magnet B chemical energy and mechanical energy C generator and motor D solar energy and geothermal energy?
C. Generator and motor. In case of generator mechanical energy is converted into electrical energy But in motor, electrical energy is changed into mechanical energy.
Why is a permanent magnet necessary for an electric motor to function effectively?
A permanent magnet is necessary for an electric motor to function effectively because it creates a magnetic field that interacts with the electric current flowing through the motor's coils, causing the motor to generate rotational motion. This interaction between the magnetic field of the permanent magnet and the electric current is essential for the motor to convert electrical energy into mechanical energy efficiently.
What does a field magnet do in a motor?
A field magnet in a motor generates a constant magnetic field that interacts with the magnetic field produced by the armature, causing it to rotate. This rotation creates mechanical energy that drives the motor. The field magnet helps establish the direction of the magnetic field within the motor, ensuring proper operation.
What is the Use of magnet in electrical fan?
The magnet in an electrical fan is used in the motor to produce a rotating magnetic field. This rotating magnetic field interacts with the coils of wire in the motor, causing them to rotate and drive the fan blades. In essence, the magnet helps convert electrical energy into mechanical energy to power the fan.
What makes electrical energy change into energy of motion?
Electrical energy can be converted into motion energy by using an electric motor. When electric current flows through the coils of the motor, it creates a magnetic field that interacts with a permanent magnet or electromagnet to generate a rotational force, causing the motor to turn and producing mechanical motion.
What is a magnet motor?
A magnet motor, or permanent magnet motor, is a hypothetical device that, if made to work, would use the attraction and repulsion properties of permanent magnets to rotate a shaft indefinitely, or until the magnetic domains disassociate. The concept of the magnet motor is contrary to several known laws of physics, including the law of conservation of energy. Advocates of such devices insist that magnets have the power to do work, but the reality is that a magnetic field has no power to do work unless energy is stored within the field, which is done by moving the magnet with an outside source, such as the movement of one's hand or an electric current. Once stored, and the motor set in motion, this potential energy is quickly converted to kinetic energy, and then to heat through friction. A magnet motor cannot rotate on its own because it produces no energy of its own, thus the very idea of the magnet motor is fundamentally flawed.

How do you convert electrical energy into mechanical energy by using a motor?
By driving electricity through the motor. The electric current generates a magnetic field; this interacts with the motor's permanent magnet to create movement.

In essence, the magnet helps convert electrical energy into mechanical energy to power the fan.
Can an electric motor work without a magnet?
No, an electric motor requires a magnetic field to function. The interaction between the magnetic field and electric current generates the force that drives the motor's motion. Without a magnet, the motor would not be able to convert electrical energy into mechanical energy.
Does a motor work?
A motor does not provide energy. It converts electrical energy to mechanical energy. From a circuit standpoint, the motor is considered a load (similar to a resistor). Resistors convert electrical energy to heat energy.
What is a permanent magnet motor?
A motor with permanent magnets rather than field coilsA:A non-functional contraption often peddled as a free-energy generator.
What makes electrical energy change into energy of motion?

How does a permanent magnet motor work and what are its key operating principles?
A permanent magnet motor works by using magnets to create a magnetic field that interacts with electric current to produce motion. The key operating principles include the attraction and repulsion of magnetic fields, the conversion of electrical energy into mechanical energy, and the rotation of the motor's shaft to generate power.
Where does a magnet draw its perpetual energy from?
A magnet does not have perpetual energy.
