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.
How does an open or split jaw amp meter work?
It puts an iron core around a conductor, which allows the meter's circuitry to sense the strength of the magnetic field. The strength of the field around the conductor is related to the amount of current flowing.
What is formed around a conductor when a current is passed through it?
A magnetic field.
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".
What is the function of field winding in DC generator?
The motor needs the current and magnetic flux to create motion The magnetic field is created by field winding where as armature carries the current resulting into the rotation of armature
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 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 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.

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.
