Do refrigerator magnets increase the energy consumption of a refrigerator due to induction?
No. A refrigerator magnet does not have a strong enough magnet field to affect your motor. Also the motor is mounted either at the top of bottom of your fridge. Far enough away from the outside of the door.
Definition of a magnet?
A magnet is a material or object that produces a magnetic field.
Why can magnets attract objects without touching them?
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
How a compass can be used to trace the magnetic field of the magnet?
The pull of the magnet will over ride the earths magnetism. So the compass will react to the magnet as it passes through its field.
What occurs if the size of the magnet is change?
If the size of a magnet is changed, it can affect the overall strength of the magnetic field it produces. Generally, a larger magnet will have a stronger magnetic field, while a smaller magnet will have a weaker magnetic field. However, other factors such as the magnet's composition and shape can also influence the strength of the magnetic field.
Where is a motor field magnet located?
The field of a motor is set up by the non-rotating part of the motor, and we call that the stator.
In an electric motor a magnetic field causes what to spin?
The rotor (which is some type of magnet).

What is a Compound Wound Traction Motor?
It is a Direct Current Motor which is wound and creates a magnetic field when energized and does not use a permanent magnet. Jeff S.
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.
Can small permanent magnet motors be reverse direction if the direction of current flow to the motor is reverse?
Permanent magnet field motors. With a these motors, a permanent magnet is used to replace the field coil. DC power is connected via the brushes, to the armature only. Reversing the polarity, will cause the motor to reverse its direction of rotation. It is very common to use a switch to intentionally reverse to the polarity, to allow reversal of the motor if desired.
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.
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.
What is a rocker arm in a DC motor and what will happen if the rocker arm connections are changed?
A rocker arm holds a carbon brush. In other words it is a carbon brush holder. Changing over the rocker arm connections is the same as changing over the armature connections and will make a DC motor turn in the reverse direction assuming that the magnetic orientation of the motor's field stays the same.More detailDC motor having a field windingIf the stator's field is created by a field winding and that winding's connections are changed over at the same time as the armature's connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's field is created by a field winding and that winding's connections are not changed over at the same time as the the armature's connections are changed over, then the DC motor will turn in the reverse direction.DC Motor having a field created by a permanent magnetIf the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is reversed at the same time that the armature connections are changed over, then the DC motor's direction of rotation will be the same as before.If the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is not reversed at the same time as the armature connections are changed over, then the DC motor will turn in the reverse direction.
What is a shape of a magnet field?
Depends on the shape of the magnet, but in general, the field is spheroid around the pole of the magnet.
