One of the ways you can detect the presence of a magnetic field is by the use of a magnetic proximity sensor. They are non-contact proximity devices that are used to detect magnetic objects.

What is the difference between the magnetic fields of horseshoe and bar magnets?
The magnetic field for a bar magnet is fairly circular around the whole of the magnet, with the north and south poles at opposite ends. The magnetic field for a horseshoe magnet, however, only arcs in front of the two ends, as both are pointed on the same end.
What field in a database is identified by a field?

When is database a field?
A databas is a field when you grow grass on it.
Who had first detected the presence of magnetic field in earth?
Albert Einstien was the first to detect the presence of magnetic field in earth
How do you find magnetic field?
One of the easiest ways to detect a magnetic field is with a length of conductive material attached to a voltage meter. The presence of a magnetic field causes an electrical current to flow through the conductor, thus causing a spike on the meter.
What instrument can detect a magnetic field?
A magnetometer
Is a device that can detect changes in the strength of the magnetic field?
answer
Can any magnet detect earth magnetic field?
Yes
What tool helps you detect earth's magnetic field?
compass
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
The presence of a magnetic field indicates that a planet may have what?
A magnetic field indicates a ferrous core. This is necessary for life to begin because a magnetic field is needed to deflect solar radiation.
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
What magnetic fild do you detect when you go hiking?
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.
