For Which Of The Regions Shown In The Figure Is The Observed Effect The Strongest?

the correct magnitude of the emf depends on the rate of change of the

What is the effect of the size of the nail on the strength of an electromagnet?

A wider nail will make the magnet stronger. Making the nail longer will not make the magnet stronger unless you also add more turns to the coil.

What effect does increasing the loop area have on the brightness of the lamp?

The brightness increases when the number of loops increases. The total magnetic flux through the pickup coil is equal to the magnetic flux through each loop times the number of loops.

What effect does increasing the loop area have on the brightness of the lamp?

What happens to the induced voltage if you increase the number of loops in the wire?

More loops mean higher induced voltage. The larger the area means more field enclosed and so the higher the voltage. The faster the changes are made, the greater the induced voltage.

How does the number of coils affect the current produced?

As the number of coils is increased the magnetic field will become stronger, because each coil has its own magnetic field, so the more coils there are the more field lines there are which means it would be a stronger electromagnet.

How does the size of the iron core affect the electromagnet?

Using larger gauges of wire on the coil will decrease this innate resistance. This will increase the current and therefore the field. Using smaller gauges will increase the resistance, reduce the current and weaken the field.

At which point along the coiled wire would a connection result in the brightest light bulb?

The light bulb is brightest when either end of the magnet is in the middle of the coil.

When the rate of motion of the same coil of wire is increased through the same magnetic field?

Increasing the speed of the relative motion between the coil and the magnet – If the same coil of wire passed through the same magnetic field but its speed or velocity is increased, the wire will cut the lines of flux at a faster rate so more induced emf would be produced.

What will be the direction of current flowing through the coil when the magnet is dropped in?

Once we know the magnetic polarity of the coil side, we can easily determine the direction of the induced current by applying a right-hand rule. In this case, the current flows in the A to B direction.

What happens when a current is passed through loops of wires using a battery or voltage source?

Current traveling through a loop of wire creates a magnetic field along the axis of the loop. The direction of the field inside the loop can be found by curling the fingers of the right hand in the direction of the current through the loop; the thumb then points in the direction of the magnetic field.

What effect does increasing the number of coils has on an electromagnet?

Increasing the number of coils, which adds more field lines and makes the electromagnet stronger.

What effect does increasing the number of coils has on an electromagnet?

What do you call a device that produces an electric current when a coil of wire is wrapped?

Produces an electric current when a coil of wire is wrapped around an iron core and rotated near a magnet. -mechanical energy is changed to electrical energy. Turbine.

How does the number of wire loops in the coil affect the strength of the electromagnet?

The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

What produces the strongest magnetic field?

The intense magnetic field of a magnetar is created by superconducting currents of protons inside the neutron star, which were established by the manner in which the matter collapsed to form a neutron star.

Which electromagnet produced the strongest magnetic field Why?

Both iron-core and superconducting electromagnets have limits to the field they can produce. Therefore, the most powerful man-made magnetic fields have been generated by air-core nonsuperconducting electromagnets of a design invented by Francis Bitter in 1933, called Bitter electromagnets.
