What happens to a compass when it is brought near a current-carrying wire?
the compass aligns with the magnetic field created by the wire
What happens when a compass is palced near a current carrying conductor?
If the conductor is carrying AC, no effect. If the conductor is carrying DC, then the compass needle will be deflected. Provided the two are close enough, and the DC current is strong enough.
What happens when you hold a compass close a wire carrying a current?
current flowing throgh a conducter or wire it emmits a circuler magnetic field around the wire.a compass react to a magnetic field by point to the north pole.(point throgh the south to the north).
What happens when a compass is placed near a current-carrying wire?
That depends. If we assume that current is flowing though the wire then there is an induced magnetic field equal to B=u_o*I/(2R*pi). For a visual refer to http://hyperphysics.phy-astr.gsu.edu/HBASE/magnetic/magcur.html#c2
What happens to the compass needle when current in the wire is switched off?
It will return to pointing North.

What happens to the current carrying ability of a wire when the temperature increases?
the current will increase
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What happens to the compass needle when the current in the wire is switched?
It will return to pointing North.
What happens to the compass needle when current in the wire is switched off?
It will return to pointing North.
What happens to the compass needle when the current in the wire is switched off?
It will return to pointing North.
What direction does a compass needle point if a current carrying wire is wrapped around it?
The compass needle aligns itself parallel to the direction of the lines of magnetic force where it happens to be. It does not 'point to a particular pole' for that is beyond the sensibility of a simple bar of metal. I repeat, it aligns itself parallel to the lines of magnetic force ...
What happens to two parallel wires carrying electric current in opposite directions?
repel each other
Describe what happens when two plates carrying continental crust collide?
Mountain Ranges form. Like the Himalayas
