What are the 6 pieces of evidence that prove the continents were once connected?
Shape, fossil animals and plants, magnetic field reversals, residual magnetic fields of rocks, subduction zones.
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Can things hover in a magnetic field?
Things that are affected by a magnetic field, such as iron and steel can hover in a magnetic field.
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
What is the space all around a magnet called?
I'm sure you mean the magnetic field
Working of a relay?
A small current controls (turns on or off) a large current. Usually performed using a coil to produce a magnetic field which opens/closes an electrical switch.
How is solenoid a magnet?
A Solenoid is an electro-magnet. It has coils of wire, usually copper. When an electric field is applied to the coils of wire, an magnetic field is generated. This magnetic field attracts a steel or iron segment on the switch and activates the switch.
Is copper wire is magnetic?
it produces a magnetic field. i think that if current is passed through the wire it can attract pieces of iron
What can you use to show the magnetic field of a magnet for people to see?
Little bits of other magnet. Iron filings - the small pieces of metal will floow the magnetic field lines.
Why are there magnetic strips on the ocean floor what do they mean?
The earth maintains a magnetic field due to the metals that make up its core. Thus, all rocks are influenced by this magnetic field and "face" the direction the field is "facing". Every few hundred million years the poles switch, and with it the magnetic field. Similarly, all rocks "face" the new direction. Magnetic strips are indicators of when the magnetic field of the Earth changed.
What is the main difference between a relay and a solenoid?
A relay is a switch - a solenoid produces a magnetic field.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
Region around a magnet in which magnetic force can act?
Magnetic freild
What are the 6 pieces of evidence that prove the continents were once connected?
Shape, fossil animals and plants, magnetic field reversals, residual magnetic fields of rocks, subduction zones.
Does Eris have a magnetic field?
no. Eris does not have a magnetic field
What is a region where a magnetic force can be detected?
The magnetic field. If it's an electromagnet, the electromagnetic field.
