How does lamination affect the magneto-motive force across the air gap of a magnetic circuit?

∙ 12y ago
It doesn't. There are three things that can affect this force: another magnetic field, another conductor within the field, and the size of the gap itself, of course.
Lamination is, in essence, insulation, and anything non-magnetic and non-conductive within the field is transparent to the field itself - it's as if it weren't there.

How will calculate the power of magnet?
The electric power is measured the same as in any other electric circuit, in watts. You calculate this by multiplying the current (in amps) by the potential difference (in volts) across the circuit. So: P = I V If you meant how do we measure the strength of the magnetic field generated, there are two different vector fields that may be called "magnetic field". These are the H-field and the B-field. The H-field may also be called the "magnetic field intensity", the "magnetic field strength", the "auxiliary magnetic field" or the "magnetising field". It is measured in amps per metre. The B-field may also be called the "magnetic flux density", the "magnetic induction", or the "magnetic field". It is measured in teslas.
Define recovery voltage in circuit breakers?
It is the transient voltage that appears across the contacts of the circuit breaker at or near the zero current instant during arcing period. A high frequency transient voltage appears across the contacts and is caused by the rapid distribution of energy between the magnetic & electric field associated with the station & transmission lines of the system at the zero current. This transient voltage is known as restriking voltage.
If three lamps are connected in series to a 6 volt battery how many volts are impressed across each lamp?
In a parallel circuit, Voltage is constant through out the circuit. Thus, the voltage across each lamp is 6-volts.
Is an open circuit dangerous?
its likely to have the full supply voltage across it
Device that produces current by moving a magnetic field across a wire?
An electrical generator does that.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
How can you tell that there is a current in a wire?
A clamp on amp meter is used for this purpose. When amperage is present in a wire there will be a magnetic field generated around the wire. The clamp on amp meter measures this magnetic field and converts it to an amperage value that is read on the screen of the amp meter. No current flow, no magnetic field, no reading. A dangerous and non recommended way to check current flow is to open the circuit when the load is connected and operating. There will be a small arc that jumps across the gap when the circuit is opened. This is current flowing in the circuit.
Do You measure current across a circuit?
A current flows through, not across, a circuit. And, yes, you can measure it using an ammeter.
What is an equation for power?
Power = (energy used)/(time to use it)Power dissipated by an electrical circuit =(voltage across the circuit) x (current through the circuit)or(resistance of the circuit) x (square of the current through the circuit)or(square of the voltage across the circuit)/(resistance of the circuit)
In which circuit is the voltage the same across all branches?
Parallel circuit.
Why the voltage in parallel circuit is the same across each circuit?
gfbvbb
How is a parallel circuit the same as a series circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
Is a series circuit the same as a parallel circuit?
In both cases, the power dissipated is measured by multiplying the voltage across the circuit by the current through the circuit.
How do magnets generate electricity?
Magnets generate electricity by moving the magnet along a conductor, such as a wire. This is called induction. When magnetic lines of force sweep across a conductor, the magnetic field induces a voltage in the conductor. Voltage is "electrical pressure" and if a supporting circuit is set up connected to that conductor, current will flow.
What type of circuit has the same voltage drop across each of its components?
A parallel circuit. Since a parallel circuit has only two nodes, there can be only one voltage difference between the nodes.
The voltage measured directly across an open switch in a circuit will be?
The voltage measured across an open in a series circuit is the equivalent of the sourse voltage.
What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
