What happens when you hold a compass close a wire carrying a current?
current flowing throgh a conducter or wire it emmits a circuler magnetic field around the wire.a compass react to a magnetic field by point to the north pole.(point throgh the south to the north).
Can an electromagnets strength be changed?
The more electricity the more powerful the magnetic field. Increase the voltage, which for the given resistance of the coil, will also increase the current and the magnetic field.
Is magnetic field strength directly proportional to the coil or the current?
The strength of a magnetic field won't be directly proportional to the turns in the coil. It is more correct to say that field strength is directly proportional to current through the windings of the coil. There are some "limiting factors" that will not allow this to be a hard and fast rule, but it is essentially correct.AnswerMagnetic field strength (symbol: H) is defined as the magnetomotive force per unit length of a magnetic circuit. As magnetomotive force is the product of the current flowing through a winding and the number of turns, then, yes, magnetic field strength is proportional to both the current and the number of turns -but this is ONLY true over the straight part of the magnetisation curve (i.e. before it goes into saturation).
What is the relationship between magnetic force and distance?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
Is the strength of an electromagnet measured in volts?
That's a tricky question. Well, technically it is not measured in volts. The strength of an electromagnet depends on the electrical current which flows through its wires, but not on what drives that current. The current is measured in the amount of charge per unit time that flows through the wires. But when it comes to measuring the magnet, you have to refer to the magnetic field. Without it, there wouldn't be any "magnet." So, logically, to measure the strength of the magnet you must first measure the strength of the magnetic field. It's strength is measured in Volts per meter(V/m). So to measure the strength of the electromagnet you must measure the strength of the magnetic field whose formula is found in the next to last sentence. Hope this helps.
What determines the strength of the magnetic field when current flows through a conductor?
Magnetic fields currently flows through a conductor is determined by multiplying the number of turns of wire by the current flow. This is what causes electricity.
What determines the strength of the magnetic field when current flows through the conductor?
"If the conductor is wound into a coil the magnetic lines of flux add to produce a stronger magnetic field... Another factor is the amount of current flowing through the wire" (from Delmar's Standard Textbook of Electricity: Fifth Edition, Unit 4 - Magnetism, pages 111-112) The strength of an electromagnet is proportional to its ampere-turns; determined by multiplying the number of turns of wire by the current flow.
What determines the strength of a magnetic field?
factors on which magnetic field a bar magnet depends :- 1. pole strength of the magnet 2. medium in which the bar magnet is present(since the permittivity changes) factors on which external magnetic field(B) of a current carrying coil depends:- 1. the amount of current flowing through the conductor 2. the perpendicular distance of the point from the conductor. 3. medium in which the conductor is present(since the permittivity changes)

What does an electric current need?
A conducter
Why nucles contributes less magnetic moment than electron magnetic moment due to spin?
Because it is about 10,000 times smaller. The magnetic moment depends on the strength of a magnet's poles, and on its separation; or, in the case of a current loop, the strength of the current, and the area it surrounds.
Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.?
No. More current will result in more magnetic field.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
What happens to the strength of magnetic force in an electromagnet when increasing the current through the coil?
The strength is increased, this is how Roller Coasters operate.
Inductive ammeters work because of what principle?
Inductive Ammeters do not make physical contact with the circuit, but measure the strength of the magnetic field surrounding the wire carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.This means that the meter probe surrounds the wire(s) carrying the current and measures the strength of the magnetic field that surrounds any conductor carrying a current.
Does a moving magnetic field produce an electric current?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
What is the relationship between magnetic fields and electricity?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
