Interpretation:
The difference between a magnetic field vector and a magnetic dipole vector is to be stated.
Concept introduction:
The region around the magnet that exerts a magnetic force is known as a magnetic field. Magnetic fields are produced by moving charged particles. These are produced around currents, electric fields, and dipoles.
Answer to Problem 16.1E
Magnetic field vector is the field produced when an
Explanation of Solution
The quantities that are expressed in terms of both magnitude, as well as direction, are known as vector quantities. The magnetic force exerted around a magnet is known as a magnetic field. The charged particles that are in motion produce a magnetic field. Any point in a magnetic field can be described in terms of its magnitude as well as the direction of the field. A current carrying wire produces magnetic field lines in the form of circles which have the same center. These circular vectors are in the form of a cylinder that has its center at the wire. Then the right-hand thumb rule gives the relation between the direction of the electric current and the direction of the magnetic field lines. According to this rule, if the thumb points towards the direction of the electric current, the direction of the fingers that are wrapped around the wire shows the direction of the field lines. If an electric charge flows around a loop, then a magnetic effect is produced. This magnetic effect is known as a magnetic dipole. Any point in a magnetic dipole can be described in terms of its magnitude as well as its direction. It corresponds to a magnetic dipole vector. Since it consists of opposite magnetic poles, it is known as a dipole.
Magnetic field vector is the field produced when an electric current passes through a current carrying wire whereas a magnetic dipole vector is a magnetic force that is produced when an electric current passes through a loop that carries current.
