# How can you determine the north and south pole of a magnet?

Unless they came marked with “N” or “S,” the poles of a magnet look the same. One easy way to tell which pole is north and which is south is to set your magnet near a compass. The needle on the compass that normally points toward the north pole of the Earth will move toward the magnet’s south pole.

## How do you determine the north and south pole of a solenoid?

Yes, the north and south poles of a current–carrying solenoid can be determined with the help of a bar magnet. If the magnet is repelled, the end is north end of the solenoid. If the magnet is attracted, the end is south end of the solenoid.

## How will you determine the north pole and the south pole of a magnet class 6?

Answer. Location of the poles of as magnet can be determined by suspending it freely. A freely suspended bar magnet always points in north−south direction. The end that points towards north direction is the north pole of the magnet while the end that points towards south direction is the south pole of the magnet.

## How do you define where the poles of a magnet are?

Scientific definitions for magnetic pole The north pole of a magnet is the pole out of which magnetic lines of force point, while the south pole is the pole into which they point.

## Which side of a magnet is north?

The end of the magnet pointing north is the negative side of the magnet. The end of the magnet pointing south is the positive side of the magnet.

## How do you determine the pole direction of a solenoid?

To find the polarity of a solenoid, you can use the right-hand rule for current (or left-hand rule for electrons since they go in the opposite direction to the current). To do this, point your right thumb in the direction that the current travels in the coiled wire in the solenoid and curl your fingers.

## How do you determine the direction of a magnetic field line in a solenoid?

Solution : The direction of the field due to coil or solenoid carrying current can be determined by using right hand rule.
When you curl your right hand fingers in the direction of current,thumb gives the direction of magnetic field.

## How can we determine the north pole of a magnet if there is no marking?

Take the bar magnet and suspend it freely with help of a thread, the end that points towards north pole will be regarded as north end of the magnet.

## Which is the north pole and which is the south pole of a magnet?

The ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other.

## Can a magnet north pole exist without a magnet south pole?

No. A magnetic north pole can never exist without a magnetic south pole.

## How does physics define the north pole of a bar magnet?

The ‘North pole’ of any magnet is the one that would be attracted to the earth’s North magnetic pole. In that sense, they are just labels that identify the opposite magnetic force produced at each end of the magnet.

## How do you determine the polarity of a magnet without a compass?

Place the north end of one magnet near the magnet with unknown poles. If the north end repels the magnet, that side is the unknown magnet’s north pole. This obviously only works if you know the polarity of one of the two magnets.

## How could you determine which pole of an electromagnet is north and which pole is south 2 3 sentences?

A: Simple! Get a compass and put it near one of the electromagnet’s poles. The end of the compass needle which usually points north will be repelled by the north pole of your electromagnet and attracted by the south pole.

## Is south pole positive or negative?

The question is, which is which? When magnets are used in magnetic therapy, the poles are often referred to as being positive or negative. Generally, the south pole is termed positive, and the north negative.

## Which side of solenoid is north?

The direction of current in a solenoid is observed from one end. If the direction of current is anti clockwise, the end of the solenoid acts as a north pole and vice versa.

## Which rule is used to determine the polarity of the electromagnet?

The polarity of this magnet can be understood with the help of clock face rule. If the current is flowing in anti-clockwise direction, then the face of the loop shows North Pole.

## Does the magnetic field of a solenoid has north and south poles?

A: Like a bar magnet, a solenoid has north and south magnetic poles and is surrounded by a magnetic field.

## What is the direction of the magnetic field line in a magnet?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

## How do you calculate polarity in physics?

In addition, for determining the polarity of a bond, you must find the difference of electronegativity of the atoms involved. Also, if the difference is amid 0.4 and 1.7 then the bond will appear polar. But, if the difference is greater than this, then the bond will have an ionic character.

## How can you determine the polarity of a current carrying?

Ans: If the current at one end of the solenoid is in the anticlockwise direction it will be the North Pole and if the current is in the clockwise direction it will be the South Pole.
