What are lines of magnetic flux?

To calculate the strength of a magnetic force on a wire you must find the magnetic flux density . This is measured in a unit called tesla. Lines are drawn to show the direction on a magnet’s north pole. They are called lines of magnetic flux, and are shown in the diagram.

What are magnetic lines of force explain their characteristics?

The magnetic field at any given point is specified by both a direction and magnitude. Magnetic lines of force start from the North Pole and end at the South Pole outside magnet. Two magnetic lines of force cannot intersect each other and they are continuous along the axis of the electromagnetic conductor.

What are the characteristics of magnetic field lines around a bar magnet?

They are continuous closed curves. They originate from the North Pole and terminate at the South Pole. Two lines do not intersect each other. They are crowded where the magnetic field is strong, i.e. near the poles.

How the magnetic flux or magnetic lines produce a flow of electricity?

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire.

What are the 4 basic properties of the magnetic lines of force?

The magnetic lines of force has the following properties:

• Each line is a closed and continuous curve.
• They originate from the north pole and terminate at the south pole.
• They will never intersect each other.
• They are crowded near the poles where the magnetic field is strong.

What is a magnet write its characteristics?

They are: Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.

What is a bar magnet write an three characteristics of magnetic fields lines produced by a bar magnet with diagram?

1) The direction of magnetic field lines outside the magnet sis from North Pole to South Pole. 2) The direction of magnetic field lines inside the magnet is from south pole to the north pole. 3) No two magnetic field lines intersect each other.

What do you mean by magnetic lines of force why two such lines do not cross each other?

The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.

How do you calculate magnetic flux?

First,determine the magnetic field. Measure the strength of the magnetic field.

What is the formula for magnetic flux?

The value of magnetic flux is a vector quantity and it depends on the direction of the magnetic field. The magnetic flux formula is given by, Where, B = magnetic field, A = surface area and. Θ = angle between the normal to the surface and magnetic field.

What does magnetic flux mean in physics?

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt-seconds), and the CGS unit is the maxwell.

What do magnetic lines of force mean?

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.
