What is someone who studies magnets called?
A magnetometer is a device used to measure the intensity and direction of a magnetic field.
What do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
What does an eletromagnet do in a motor?
Provide amoving magnetic force field.
What happens to the magnitude of a magnetic field if the electric field that induces it increases the rate at which it changes?
The magnitude of the magnetic field is decreased
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
Which device does not have a magnetic field?
the device is a dedle on compass
What is electro -magnetic force?
Magnetic force is present around the electric field which is also known as electro-magnetic field.
Is a device that can detect changes in the strength of the magnetic field?
answer
A device that uses the Earth's magnetic field to indicate which way North is?
That is called a magnetic compass.
A device that produces a magnetic field by wrapping wire into a coil is a?
an electromagnet
What do you call a device to measure relationship to earth's magnetic field?
A compass
A device that produces a magnetic field by an electric current?
Any device with an electrical current will create a magnetic field. A tube of wire coils with a current running through it is called a solenoid and it will produce a magnetic field through the inside of the tube, as well as around it... Sorry, not much for physics.
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
What device produces a magnetic field froma moving electrical charge?
magnet
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
How do you reverse reverse polarity?
Earth's magnetic field lines up in a direction opposite of the present magnetic Feld
Device that produces current by moving a magnetic field across a wire?
An electrical generator does that.
