Does electric currents cause coils in magnetic fields to move?
yes, electric feilds do cause the magnetic feilds in the coils, this was first observed by Hans Oersted in 1819. He showed that when an electric current was passed theough a wire a nearby compass needle showed a deflection, this prooves that an electric feild causes an magnetic feild.
Does a cold planet's core have magnetic fields?
It MIGHT have. If the SURFACE of the planet is cold, its interior can still be liquid, for billions of years - allowing the currents that cause the magnetic field. Note, for example, that Jupiter has considerable magnetic fields.
Do electric fields include magnetic fields?
No. While the two may be induced by the same cause and are related phenomena, they are not identical.
What cause the sun's magnetic field?
Magnetic fields are created by electric currents that are spread throughout the entire solar system. This current causes the sun to ebb and surge on its surface. The polarity of the field is flipped when at its peak during a peak of high sunspot activity.
What do you do to turn sound waves into small electric currents so they can be recorded?
Use a microphone. Sound waves cause small vibrations of a diaphragm which disturbs an applied electric or magnetic field, which causes small currents in pickup circuitry.
What is the cause of an electric current?
Electric currents are caused by voltages.
Can people have magnetic fields that cause computers to malfunctionAlso?
No.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
Does moving an electric current cause a magnetic field?
yes
Why is a vibrating electric field an example of an electromagnetic wave?
The changing electric field will produce a magnetic field; the changing magnetic field will cause an electric field; both will propagate as a wave - an electro-magnetic wave.
