Why magnetic field at the center of bar magnet is zero?

Why? The centre is at equilibrium with the same amount of magnetic force pulling it to the North and the South poles. Equal number of magnetic lines originate towards the North and South poles so exerting equal proportions of the opposite fores. Thus it has zero magnetism.

Where is the magnetism in the magnet zero?

center
The resultant magnetic field at the center of a bar magnet is zero.

Why is the magnetic field zero?

A current produces a magnetic field that is everywhere proportional to the magnitude of the current. At the center of a current-carrying conductor of finite radius, a circle of zero radius encloses zero current, therefore there is zero magnetic field.

Where is the magnetic field the strongest on a bar magnet?

the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)

What is WB physics?

In physics, the weber (/ˈveɪb-, ˈwɛb. ər/ VAY-, WEH-bər; symbol: Wb) is the SI derived unit of magnetic flux. A flux density of one Wb/m2 (one weber per square metre) is one tesla. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891).

Where on a bar magnet is the magnetic force the maximum?

Hence magnetic force of lines are more crowded at the poles compared to the centre of magnet and hence strength of magnetic field at north and south pole magnet is more compared to centre of magnet. And therefore magnetic force is maximum at both the poles of the magnet compared to the centre of magnet.

Why the magnetic field is zero outside the solenoid?

The magnetic field lines exist outside the solenoid, but the number of field lines per unit area (flux) outside the solenoid is much less compared to the number of lines per unit area (flux) inside the solenoid. Hence the magnetic field outside is so weak that it is considered to be practically zero.

Can a magnetic force be zero?

If the particle velocity happens to be aligned parallel to the magnetic field, or is zero, the magnetic force will be zero. This differs from the case of an electric field, where the particle velocity has no bearing, on any given instant, on the magnitude or direction of the electric force.

What causes a magnetic field in a bar magnet?

Magnets are different because the molecules in magnets are arranged so that their electrons spin in the same direction. This arrangement and movement creates a magnetic force that flows out from a north-seeking pole and from a south-seeking pole. This magnetic force creates a magnetic field around a magnet.

Where is the magnetism strongest on a bar magnet?

pole
The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.

What is the magnetic field at the center of a bar magnet?

The magnetic field at the center of a bar magnet is zero in ideal case. The field lines near the center is parallel to the bar magnet. The density of the field lines is maximum at the poles of the bar magnet and zero at the center which means that the magnitude of the magnetic field is small at the center. So, zero is the correct answer.

Why is the center of the Earth Zero magnetism?

The centre is at equilibrium with the same amount of magnetic force pulling it to the North and the South poles. Equal number of magnetic lines originate towards the North and South poles so exerting equal proportions of the opposite fores. Thus it has zero magnetism.

Why is the magnetic field at the poles of a magnet?

Any where else they are slightly divergent. There is a higher density of field lines at the edges of the poles, and thus a stronger force on the plate Figure A. Meaning the magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole.

How do you reverse the polarity of a bar magnet?

In a bar magnet, the polarity is North at one end. As you move towards the other end, the power of the magnet reduces. Now, at the other end the polarity has to be South, which is the exact opposite of North. To reverse the polarity, the magnetic state has to become zero, to attain the opposite polarity.
