"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.

Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
Explain what happens when a long straight conductor is moved through a uniform magnetic field at a constant velocity Assuming that the conductor moves perpendicularly to the field?
Interesting question. Because Fleming's right hand rule tells us that a conductor carrying a current perpedicular to a magnetic field will move in a particular direction we know that movement, current and magnetic field are related. So if we take the current away and instead force the conductor to move as described then we would observe a current in the wire. However, you have not said that your conductor is connected in a circuit - in which case the charge carriers in the conductor will tend to one side like a bar magnet.AnswerThe original answer is incorrect. A voltage would be induced into the conductor. No current would flow unless the conductor forms a continuous circuit.
When a electrical current is generated in a conductor by placing it in a magnetic field the process is known as?
Electromagnetic Induction
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 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.
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.
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)
Does a change in the flow of current through a conductor causes a change in the electromagnetic field surrounding the conductor?
Yes. The strength of the magnetic field surrounding a conductor is proportional to the magnitude of the current in the conductor.
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.
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.
Why does current carrying conductor experience force when kept near a magnet?
The current carrying conductor has a magnetic field of of its own so when it comes in contact with with another magnetic field it experiences a force which is given by fleming's left hand rule.The force depends upon :direction and the strength of the magnetic fielddirection and the strenth of the current
How a magnetic field is created and how its strength is affected?
Through a current in a conductor; it is strengthened once by making a coil of the conductor and then by inserting an easily magnetized core inside the coil
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
