What is the direction of needle when it comes to rest?

What is the direction of needle when it comes to rest?

Working The compass is kept at the place, where we wish to know the direction. Its needle indicates the North-South direction, when it comes to the rest.

What is the orientation of a free floating magnetic needle?

A free floating needle always aligns itself to the ‘magnetic north pole’ of the earth. The North Pole faces the ‘North Pole’ of the earth and vice versa.

Why does a magnetic compass needle Orient in any random direction when placed at a magnetic pole of the earth?

The earth has only vertical component of its magnetic field at the magnetic poles. Since compass needle is only free to rotate in horizontal plane where H = 0, hence the compass needle may stay in any direction.

Where will a pivot magnet point?

The end of a freely pivoted magnet will always point in the North-South direction. The end that points in the North is called the North Pole of the magnet and the end that points South is called the South Pole of the magnet.

When a freely suspended magnetic needle comes to rest it points in?

A freely suspended bar magnet always comes to rest in the North−South direction. The north facing end of the magnet is its north pole, and the south facing end is its south pole (as shown in the given figure).

Where does the compass needle point at rest?

A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth’s built-in magnet.

What does a magnetic needle do?

: a narrow strip of magnetized steel that is free to swing around to show the direction of the earth’s magnetic field The magnetic needle in a compass always points north.

Which direction does the magnetic needle of the compass show?

The magnetic pole of a compass needle is defined to be the “north-seeking” end, i.e., the end that “seeks” (points generally toward) the north geographic pole.

Which direction will a magnetic needle show on the geographic North Pole?

Answer: Magnetic compass needle always points towards the magnetic north pole of the earth. When compass is at the earth’s geographical north pole ,it points towards the north pole.

What makes a magnetic needle lie parallel to the magnetic field?

A magnetic needle lying parallel to the magnetic field required W units of work to turn it through an angle 45 o. The torque required to maintain the needle in this position will be M is the magnetic dipole moment and B is the magnetic field. Was this answer helpful?

Why does the North Pole of a needle float northward?

Though the north pole of the needle is attracted northward, the entire needle doesn’t float northward because the other end is attracted southward. The net force on the needle is zero. By what mechanism do the iron fillings shown about a magnet align with the magnetic field. There are two factors involved.

What kind of magnet is a compass needle?

The compass needle is a tiny bar magnet, and by letting it spin freely on the tip of a (vertical) needle, it has minimal friction and can orient itself along the magnetic field lines.

What happens when a compass is placed in the middle of a magnet?

If a slot is cut in to the central region to place the compass in the literal middle of the magnet, the field orientation of the original magnet again changes, but the overall NS polarity still remains the same and north of compass shall hook up with south of the magne…
