The needle of a compass will deflect from its original position when a wire carrying an electric current is placed across it. This is due to the magnetic field created by the current in the wire, which interacts with the magnetic field of the compass needle, causing it to move.

What happens if the compass is placed under the wire?

Placing a compass under a current-carrying wire can cause the needle to deflect due to the magnetic field produced by the electric current. This phenomenon, known as the right-hand rule, demonstrates the relationship between electric current and magnetic fields.


Describe what happens when you hold a compass close to a wire carrying a current?

When a compass is held close to a wire carrying a current, the magnetic field produced by the current will deflect the compass needle. This happens because a magnetic field is generated around the wire due to the flow of current, and the compass needle aligns itself with this magnetic field. The deflection of the compass needle can be used to determine the direction of the current in the wire.


What happens when a compass is palced near a current carrying conductor?

When a compass is placed near a current-carrying conductor, the magnetic field produced by the current can interact with the compass needle, causing it to deflect from its original position. This phenomenon is known as the magnetic field produced by the current affecting the magnetic needle in the compass. The direction of the deflection will depend on the orientation of the current and the compass in relation to each other.


What happens to a compass when it is brought near a current-carrying wire?

When a compass is brought near a current-carrying wire, the magnetic needle of the compass will align itself perpendicular to the wire due to the magnetic field created by the flowing current. This effect is known as the right-hand rule for electromagnetism.


Describes what happens when hold a compass close to wire carrying current?

When a compass is held close to a wire carrying current, the magnetic field created by the current induces a magnetic field around the wire. The compass aligns with this magnetic field and its needle will deflect in a direction perpendicular to the wire. This can be used to determine the direction of the current flow in the wire.

What happens to two parallel wires carrying electric current in opposite directions?

repel each other


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 current carrying ability of a wire when the temperature increases?

the current will increase


What happens to a current-carrying wire when placed in a magnetic field?

When a current-carrying wire is placed in a magnetic field, a force is exerted on the wire due to the interaction between the magnetic field and the electric current. This force causes the wire to move or experience a deflection, depending on the orientation of the wire and the magnetic field.


Why do we get shocked and how does it happen?

We get shocked when we come into contact with an electric current. This happens when electrons flow through our bodies, causing a sudden discharge of electricity. The shock can occur when we touch a live wire or an object that is carrying an electric charge.


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.
