When it comes to magnets opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.

What is magnetic lines of force in physics?

Magnetic Lines of Force is a an imaginary line representing the direction of magnetic field such that the tangent at any point is the direction of the field vector at that point.

In what direction do the magnetic lines of force extend outside the magnet?

Outside the magnet the magnetic lines of forces pass from north pole to the south pole and inside the magnet they pass from south to the north pole.

Does magnetic field go from south to north?

A magnetic field flows from the North to the South Pole in the same way that electric fields flow from positive to negative charges. However once cannot isolate magnetic poles as one can isolate electric charges.

In which direction do the magnetic field lines point near the south pole of a magnet chegg?

Magnetic field lines point away from the south pole of a magnet and towards the north pole of a magnet.

What is the direction of magnetic lines of force produced by passing a direct current in a conductor?

The lines of the magnetic field will be perpendicular to the flow of current on one side according to the “right hand rule” convention. The length of the region near the surface of the conductor will be the strongest and will decrease as the distance from the conductor increases.

How are the magnetic field lines near the south pole?

How are the magnetic field lines near the south pole of a magnet affected when a second south pole is brought near it? The field lines bend away from the second south pole. … The field lines go out of Earth near Antarctica enter Earth in northern Canada and are not aligned with the geographic poles.

How Earth creates its magnetic field?

On Earth flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on Earth.

What happens if Earth loses its magnetic field?

Without it life on Earth would be over very quickly. … The Earth’s magnetic field protects us by deflecting much of the incoming solar radiation. Without it our atmosphere would be stripped by solar winds. We’d be bombarded with vast amounts of radiation.

What gives the Earth its magnetic field?

Scientists know that today the Earth’s magnetic field is powered by the solidification of the planet’s liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron creating powerful electric currents that generate a magnetic field stretching far out into space.

What is the direction of magnetic lines of force in a bar magnet?

∴ The magnetic lines of forces inside a bar magnet are from south-pole to north-pole of the magnet.

What is the direction of magnetic field lines inside and outside the magnet?

(a) The direction of magnetic field lines outside a bar-magnet is from North seeking pole to south seeking pole while inside the magnet it is from south to north seeking pole.

What is the direction of magnetic field in a magnet?

The lines of magnetic field from a bar magnet form closed lines. By convention the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials.

What is the difference between the north and south pole of a magnet?

Magnets are objects that can either attract or repel other magnets. … The main difference between north and south pole is that a north pole is attracted towards the south pole of another magnet while a south pole is attracted towards the north pole of another magnet.

Where is the true north?

the geographic North PoleTrue north is the direction that points directly towards the geographic North Pole. This is a fixed point on the Earth’s globe.

Is the North Pole actually the south pole?

Compasses point to the magnetic North Pole. However what we call the Magnetic North Pole is actually a south magnetic pole. … Because Earth’s Magnetic North Pole attracts the “north” ends of other magnets it is technically the “south pole” of the planet’s magnetic field.

What happens to a compass at the south pole?

In much of Antarctica a compass needle does its best to point straight up which makes it useless for finding direction. The south magnetic pole is currently about a hundred miles north of the coast of Antarctica west of Dumont d’Urville Station. At this point a magnetic compass is theoretically completely useless.

What are magnetic lines of force and magnetic field?

The magnetic lines of force indicate the region in which the force of the magnet can be detected. This region is called the magnetic field. The magnetic lines of force or flux leave the north pole and enter the south pole.

How the magnetic lines of force are originated from north to south outside the magnet and from south to north inside the magnet?

Magnetic field lines originate from the north pole and terminate at the south pole outside of a magnet. They form continuous closed curves. The direction of the magnetic field lines inside the magnet is from south pole to north pole. … It gives the force direction.

Where is Earth’s magnetic north pole located?

The Magnetic North Pole (also known as the North Dip Pole) is a point on Ellesmere Island in Northern Canada where the northern lines of attraction enter the Earth.

Do compasses always point north?
