How is mechanical force produced on a wire when it is passed through a wire in a magnetic field?
The movement through a magnetic field will induce a voltage; if there is a closed circuit, that will produce a current. The current, in turn, will have a magnetic field, which will interact with the external magnetic field. The direction of the interaction will be such that energy is conserved, i.e., it will tend to slow the wire down.
Physical significance of magnetic dipole moment?
The magnetic dipole moment represents the strength and orientation of a magnetic field produced by a current loop or a magnet. It is a measure of the ability of an object to interact with an external magnetic field. This property is fundamental in understanding the behavior of magnetic materials and the interactions between magnetic objects.
What is a magnetic current?
A magnetic current is a theoretical flow of magnetic energy or field. It is not a well-established concept in mainstream physics, as magnetic fields are typically described in terms of magnetic fields and their interactions with electric currents.
How are magnetic poles created?
Magnetic poles are created by the alignment of electrons in a material. When the electrons in a material align in the same direction, they create a magnetic field with a north and south pole. Some materials have intrinsic magnetic properties due to the alignment of their electron spins, while others can be magnetized by exposing them to an external magnetic field.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
Which device measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
A galvanometer measures current by using the deflections of a coil of wire placed in a permanent magnetic field.
What measures current by using the deflections of a coil of wire placed in a permanent magnetic field?
A galvanometer measures current by deflecting a coil of wire in a magnetic field. The current flowing through the coil generates a magnetic field that interacts with the permanent magnetic field, causing the coil to deflect. The amount of deflection is proportional to the current strength flowing through the coil.
What is a fluxmeter?
meter that measures magnetic flux by the current it generates in a coil
What are rocks that exhibit magnetism that is opposite to the current magnetic field?
Rocks that exhibit magnetism opposite to the current magnetic field are referred to as antiferromagnetic or diamagnetic. This means that the magnetic moments of the atoms or ions within the rock align in such a way that they oppose the external magnetic field applied. Antiferromagnetic materials have equal but opposite magnetic moments whereas diamagnetic materials create a magnetic field opposite to the external field.
What are continental deflections?
When a continent deflects the movement of a current.
What would happen if the direction of the current through a hall probe is reversed?
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
How does a galvanometer use a magnetic field to indicate the strength of an electric current?
A galvanometer consists of a coil of wire suspended in a magnetic field. When an electric current passes through the coil, it generates a magnetic field that interacts with the external magnetic field, causing the coil to move. The amount of deflection is proportional to the current strength, allowing the galvanometer to indicate the current passing through it.
What is turned in a galvanometer?
A galvanometer measures small electric currents and it typically consists of a coil of wire suspended in a magnetic field. When current flows through the coil, it generates a magnetic field that interacts with the external magnetic field, causing the coil to rotate, which is then indicated on a scale to show the current strength.
What instrument measures the direction of current?
A compass can be used to measure the direction of current flow in a circuit by aligning the compass needle with the magnetic field created by the current.
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.
What type of magnet is temporary?
A temporary magnet is one that only exhibits magnetic properties when subjected to an external magnetic field. When the external field is removed, the temporary magnet loses its magnetism. This can be achieved with materials like soft iron or electromagnets.
