yes,it would


Can you deflect metal with magnetism?

Only if 1) the metal is magnetic (Iron, Nickel, Cobalt or magnetic alloys) or 2) the metal is carrying current


How does a compass needle respond when a compass is places within a magnetic field?

A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.

When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?

This proves that a magnetic field is developed around the conductor wen current flows through it...


Can a electric current be used to deflect a compass needle?

Can an electric current be used to deflect a compass needle?

Yes.


Does a radio alter a compass reading?

The pointer on a compass is magnetic. The speakers and transformers a radio put out magnetic fields that WILL deflect the direction that the pointer points. - wjs1632 -


Can a electric current affect a compass?

Yes. An electric current is surrounded by a magnetic field, and this will affect a compass. Please note that this is more noticeable in the case of DC - for AC, the current changes all the time, it changes very quickly, and the AVERAGE value of the magnetic field is zero.
