A compass needle placed near a current-carrying wire shows deflection because the moving charges in the wire create a magnetic field around the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align with the direction of the current flow in the wire.
What else can I help you with?
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.
When the free ends of a tester are dipped into a solution the magnetic needle of a compass shows deflection. Can you explain the reason?
The deflection of the magnetic needle in the compass is due to the flow of electric current when the free ends of the tester, such as a galvanometer, are dipped into the solution. The electric current creates a magnetic field around the tester, which interacts with the Earth's magnetic field, causing the needle in the compass to show deflection.
What happens to the needle of a compass as a wire carrying electric current is placed across it?
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.
Why does a compass needle move when placed near a wire carrying an electric current?
A compass needle moves near a wire carrying an electric current due to the magnetic field generated by the flow of electrons in the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align itself with the direction of the current flow.

What will be deflection in compass needle of a magnet when a current carrying wire is placed over it?
The compass needle will turn until it's perpendicular to the wire, provided the current in the wire is enough to generate a magnetic field around the wire that's strong enough to swamp out the effects of the Earth's magnetic field. (That doesn't take much current.)

Why does a compass change direction when it is near a current-carrying wire?
A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.
Compass needle move when a current switched on?
this is because of magnetic field formed when the current flows through it. this is called electromagnetism. if we move the compass needle away from current carrying conductor or wire it returns to its position (north south position)
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 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).
How could you change the direction in which a compass needle points using a cell and a piece of wire?
The compass will react to magnetic fields, and magnetic fields are caused by currents. Therefore, holding a current-carrying wire close to the compass is enough to change the direction in which it points.The compass will react to magnetic fields, and magnetic fields are caused by currents.

Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
