# What Is The Direction Of The Magnetic Field B A At Point A

What Is The Direction Of The Magnetic Field B A At Point A. At a particular instant, an electron moving Determine the magnetic moment of the loop. That magnet will align with the direction of the magnetic To determine this, we would have to know what is generating the magnetic field.

Magnetic fields can illustrated by magnetic flux lines. ÎA vertical wire carries a current and is in a vertical magnetic field. The direction of a magnetic field at a point is determined by placing a small compass needle. Current is generally defined as the rate of flow of charge.

## This is at the AP Physics level.

Explanation: A magnetic force only occur, in a magnetic field, when a particle is moving perpendicularly relative to the magnetic field. The magnetic field points out the page and is represented with dots (•). The differential forms of these equations require that there is always an open neighbourhood around the point to which they. PPT – Magnets and the magnetic field Electric currents …

### Current is generally defined as the rate of flow of charge.

These magnetic fields can be investigated by looking at the effects of the forces The compass needle points in the direction of the Earth's magnetic field, or the magnetic field of a magnet. Strategy The magnetic force on a current-carrying wire in a magnetic field is given by For part a a. bends upward; b. bends downward. And it says over here press space.

At that point the magnetic field is along the tangent which means that if you place a compass at that point the compass will align itself along the tangent as shown below. The differential forms of these equations require that there is always an open neighbourhood around the point to which they. These lines of B form loops around the current.

### If it is a wave, the magnetic field is perpendicular to both the.

Alternatively, you place a small magnet, such as a compass, at the point under consideration. To determine the direction of the magnetic field generated from a wire, we use a second right-hand rule. Even if this magnet is kept in isolation from other magnetic fields, there is a magnetic field of earth always around it.

At that point the magnetic field is along the tangent which means that if you place a compass at that point the compass will align itself along the tangent as shown below. The compass needle deflects by an angle q to point in the direction of the net horizontal magnetic field. Explanation: A magnetic force only occur, in a magnetic field, when a particle is moving perpendicularly relative to the magnetic field.

We decided the direction of the magnetic field at any point is going to be a direction in which the north pole of a magnet would experience a force. Alternatively, you place a small magnet, such as a compass, at the point under consideration. Magnetic field lines are the lines in a magnetic field the tangent of which at any point will give the field direction at that point and its density gives the magnitude of the field.
