What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
a galvanometer.
Is megger related to hot wire instrument moving coil or moving iron?
It is related to moving coil type instrument
Why is phosphor- bronze wire used in moving coil galvanometer?
restoring torque is k theta the value of k depends upon the nature of the material used for suspension strip value of k is very small for quartz or phosphor bronze so in galvanometer phosphor bronze wire is used.
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
What is turned in a galvanometer?
The suspending coil of wire gets turned by a torque due to flow of current though it. This torque is due to Lorentz force acting on the two arms of the rectangular coil.
Write the construction of a moving coil galvanometer?
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
What describes the production of an electric current by moving a loop of wire through a magnetic field or moving a magnet through a wire loop?
moving a loop of wire through a magnetic Field. The rotation of a coil of copper wire trough a magnetic field changes magnetic field as "seen" from the coil inducing an alternating current.
What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
a galvanometer.
An electrical generator works by moving a coil of wire relative to?
An electrical generator works by moving a coil of wire relative to a magnetic field.

It is related to moving coil type instrument
Why is phosphor- bronze wire used in moving coil galvanometer?
restoring torque is k theta the value of k depends upon the nature of the material used for suspension strip value of k is very small for quartz or phosphor bronze so in galvanometer phosphor bronze wire is used.
What happens to copper wire because of the moving magnet?
The copper wire carries an electric current.
What causes the loops of wire and the pointer to move in a galvanometer?
The electromagnet's coil is attached to a pointer. When a current is in the electromagnet's coil, a magnetic field is produced. This field interacts with the permanent magnet's field, causing the loops of wire and pointer to rotate.
What does copper wire and magnets have to do with Electricity?
a magnet moved through a copper coil makes electricity
What is turned in a galvanometer?
The suspending coil of wire gets turned by a torque due to flow of current though it. This torque is due to Lorentz force acting on the two arms of the rectangular coil.
What heat can a small copper coil produce at 120 volts?
Need to know what the size of the wire is in the coil and the physical diameter of the coil.
How much voltage would be produced by 600 turns of copper and a neodymium magnet?
That depends on how fast the magnet and wire coil are moving relative to each other. Without that no answer can be given.
