Magnetic Effects of Electric Current: Compass Needle Deflection
Deflection of magnetic compass sorrounded by alternating poles
The compass needle suffers deflection because a current carrying wire produces magnetic field lines around it. This is known as magnetic effect of current.
Sketching Fields Use arrows to show the direction of compass needle deflection.
Electric current will not be able to generate magnetic field to deflect a needle. compass
Field Due To A Current Carrying Wire Deflection of a compass needle near a current carrying
... due to magnetic effect of electric current, produces magnetic field around it, which causes the deflection of magnetic needle.
If the compass needle is placed just above the conductor, the North Pole of the needle deflects towards East when the current is from South to North.
As we know a magnetic needle can only be deflected by another magnet field. So, it can be confirmed from the above experiment that the current must create ...
He then experimented on this phenomenon rigorously to found that the needle deflection was always in the direction of a tangent to a circle drawn with ...
The flux lines are in the direction shown, as determined by the right-hand grip rule. Others have illustrated how this works. With the specified orientation ...
Also, the deflection increased when a) the current got higher, b) the compass brought closer to the wire, carrying current. The deflection decreased on ...
Compass and conductor with direct current. If the battery is disconnected, the north end of the compass needle will point to magnetic north, as illustrated ...
The terminals of the loop are detached from the Magnetic battery and reconnected to
With the switch open, a straight section of the conductor is supported above the compass in the vertical plane of the compass needle.

... through the conductor is reversed, the compass needle will point in the opposite direction, indicating the magnetic field has reversed its direction.
In a laboratory exercise, you place a compass d=2.50 cm from a wire
When he passed the current through the wire in the opposite direction, the compass needle deflected in the opposite direction.
The compass needle is then deflected. Oersted showed that a behaves like a magnet when a current flows through it. Change

... the needle shows no deflection and it points in the N-S direction (i.e. along the earth's magnetic field). In this position, the needle is parallel to ...
As the wire moves closer to the compass, the deflection of the compass needle increases. When the wire is far away from the compass, the compass needle is ...

With the more powerful battery, the needle moved in a more dramatic and consistent fashion:
If the current is strong the lines will be circular. The arrows on the circular lines show the direction of the magnetic field.
We take a thick insulated copper wire and fix it in such a way that the portion AB of the wire is in the north-south direction as shown in fig.

Oersted also pointed out that when the wire was adjusted below the needle, the deflection
The magnetic field encircles this straight piece of current-carrying wire; the magnetic flux lines having no definite “north” or “south” poles.
If the solution is a bad conductor of electricity, the magnetic needle does not deflect. (Alternately, we could use the LED tester too)

Look at the figure given below and answer whether the compass needle will show deflection or not when the switch in the circuit shown is closed?
Answer: No the compass needle will not show deflection even though the switch is closed, because there is no source of electric current.
