#### exists and is an alternate of .

field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.

# How do you calculate the magnetic field strength in a coil?

Magnetic field strength in a coil can be measured from the equation :-F=I*B*L\nWhere,\nf=magnitude of Lorentz Force\nI=Current Flowing Through the Coil\nL=Length of the wire\n

# Why there is an induce current in a coil when a coil is compressed in a magnetic field?

compressing a coil in a magnetic field means that there is arelative movement of the the said coil existing in a magneticfield, hence current will be induced. induction law.

# The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?

If the coil encloses an iron rod, then the magnetic field strengthinside a current-carrying coil will be increased. This occursbecause the air path in the coil is made shorter

# How do you increase the magnetic field in a coil?

The easiest way would be to increase the current flow. After that use thicker wire for the coil or add more turns.

# Coil of wire that produces a magnetic field?

That is known by different names, including coil, and inductance.

# What is used instead of field coils in an electric motor?

permanent magnets

# How does a field coil speaker work?

A: A speaker has a magnet and the wire is suspended in a zone by a cone whereby +/- current will make the coil move up or down moving the coil and moving the cone causing air

# Why there is an induced current in a coil when a coil is compressed in a magnet field?

Whenever a conductor passes through a magnetic field, a voltage ( not current!) is induced.

# What happens to the magnetic field of a coil if an iron core is placed in the middle of the coil?

When a core is placed in the middle of the coil, the electromagnetism power of the coil will increase because the iron core is highly permeable.

# Can a silver coil make a magnetic field?

It is the flow of ELECTRICITY that makes the field in a coil.Therefore a coil of any conductor will make a field. Silver is aconductor.
