Since eEH= e(V X B) As magnetic field increases the lorentz force acting on the carriers increases which in turn increases the hall field associated with the carriers and hence hall voltage increases as magnetic field is increased.

What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?

The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.


Does increasing current on a wire increase the magnetic force acting on it?

Yes, increasing the current in a wire will increase the magnetic force acting on it. This is described by the right-hand rule, where the direction of the magnetic force is perpendicular to both the current flow and the magnetic field. Increasing the current increases the strength of the magnetic field around the wire, leading to a stronger magnetic force.


Hall effect can be used to measure?

Hall effect can be used to measure the strength of a magnetic field. When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field. By measuring this Hall voltage, the strength of the magnetic field can be calculated.


Primary voltage is 5V and secondary is 30V the primary magnetic field is 15N what would the secondary magnetic field be?

This is a trick question. A transformer transforms voltage and currents. The magnetic field strength of 15 Newtons (a measurement of force, or power) is not changed - in other words what you put into a transformer (in terms of power) you get out the other side (minus losses). so 15N in, 15N out. You can also think of it this way: voltage is applied to the primary side, which induces a magnetic field. This magnetic field induces a voltage in the secondary side. So the magnetic field produced in the primary side is the same magnetic field that produces the secondary voltage. Thus the answer is in the question - the magnetic field is 15N (there's only one).


Does voltage play a role in an electromagnet?

Voltage is the "pressure" that pushes electrons thru a circuit, higher voltage means more current, or amperes. Amperes and the number of turns of wire in the magnet control the force of the magnet

What happens to the magnetic field if the current in the wire increases?

If the current in the wire increases, the magnetic field also increases.


In an electromagnet the magnetic force increase as increase?

Adding more coils will make the magnetic field stronger. Magnetic field increases.


What is the relationship between the induced voltage in a two-coil system and the magnetic field strength?

The induced voltage in a two-coil system is directly proportional to the magnetic field strength. As the magnetic field strength increases, the induced voltage in the coils also increases.


Do the induced voltage increase in a transformer when the magnetic field strength increase?

Yes, the more voltage you put in the more you get out. If the transformer is a 2 - 1 ratio and you put 240 in you get 120 out and when you put 480 in you get 240 out. Magnetic field strength and voltage have a direct relationship. +++ The field strength is actually a function of current, although as you say, increasing the voltage will increase the current hence the magnetic field.

It increases as the current increases.


How does increasing the voltage of a supply in a electromagnet affect the strength of the magnetic field?

Increasing the voltage of a supply in an electromagnet increases the current flowing through the coil, which in turn increases the strength of the magnetic field produced by the electromagnet. This is because magnetic field strength is directly proportional to the current flowing through the coil.


What does a step up transformer do to increase the voltage of an electrical current?

A step-up transformer increases the voltage of an electrical current by having more turns in the secondary coil than in the primary coil. This causes the magnetic field to induce a higher voltage in the secondary coil, resulting in an increase in voltage.


How does voltage affect the formation and functionality of an electromagnet?

Voltage affects the formation and functionality of an electromagnet by determining the strength of the magnetic field produced. Higher voltage results in a stronger magnetic field, which increases the magnet's ability to attract or repel objects. Conversely, lower voltage produces a weaker magnetic field. This relationship between voltage and magnetic strength is crucial in determining the electromagnet's performance and efficiency.


What would happen to the voltage and the magnet is withdrawn from the coil?

When the magnet is withdrawn from the coil, the magnetic field within the coil will decrease, inducing a voltage in the coil. This induced voltage will create a current in the coil that flows in such a way as to try to maintain the original magnetic field.

In an electromagnet the magnetic forces increase as this increase?

In an electromagnet, the magnetic forces increase as the current flowing through the coil increases. This is because the magnetic field strength is directly proportional to the amount of current flowing through the coil.
