What energy is produced when a coiled wire is spun around a magnet?
Electrical
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.
How does coiling a wire affect the magnetic field generated an electromagnet?
Coiling a wire increases the magnetic field of an electromagnet because the magnetic field around a wire is circular and perpendicular to the wire. Each turn of the wire reinforces the field of the one next to it. The magnet field is strengthened. (I was in A+, too ;) ) - Dawn Ayers
Does silver stick to a magnet?
A magnet does not normally stick to silver. However a current of electricity passing through silver wire will produce a magnetic field around the wire. That electric field would have an effect on a magnet, the principle of a solenoid switch. Copper is usually used in such switches as it is cheaper but silver could be used.
Can iron be made into a permanent magnet?
take a block of iron and then coil some wire around it, then attatch it to a power source and your iron block will act as a magnet due to the magnetic field produced by the coil. the more coils you have, the stronger the magnet and vice versa. in order to create a strong magnet you'll need to produce around 8 or 9V of electricity, so a standard 9V battery should work fine.
What is produced whencoiled wire is spun around a magnet?
An electro magnet!

How does the electromagnet work?
In layman's terms; a magnet has a natural magnetic field around it. This field interacts with iron based materials, like steel (but not stainless steel, or aluminum) and when a piece of steel is adjacent to the magnet's attractive pole, they stick together. When current (electricity) flows through a conductor (piece of wire) a magnetic field is produced, similar to a regular magnet. If a piece of wire (with current flowing through) is wrapped around a magnet, the Electromagnetic field that occurs around the wire joins and strengthens the magnetic field of the magnet, thus strengthening the overall magnetism. So when you see a crane picking up and dropping junk cars, they are simply turning on & off the flow of electricity through the coils of wire wrapped around the magnet doing the work.
Do field lines around a current wire look different from those around a bar magnet?
Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end. The field lines around a current-carrying wire are circles, with the wire passing through their centers.
What is produced around a wire that has a current?
Magnetic field.
What is the A magnet that has coils of ccurrent-carrying wire around an iron core?
The current produces the magnetic field; such a magnet is called an electromagnet.
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.

When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
What causes a magnetic field to be produced around a wire?
Current flows through a wire and produces a magnetic field.
How can electricity produce by using magnet?
Electricity is generated when a piece of conductive metal (such as copper) is passed through a magnetic field (or if the magnetic field is moved around the metal). A generator will have a copper wire in the center, surrounded by a magnet shaped like a torus (donut shaped, wire is in the hole in the middle). The wire is stationary. Electricity is generated when the magnet is spun (moving the magnetic field around the wire). This will generate an AC current (alternating current).
