What else can I help you with?
Do electric and magnetic lines of force physically exist?
The "lines" of latitude, longitude, reasoning, electric fields, and magnetic fields are imaginary.
What are magnetic lines of force called?
Magnetic lines of force are called magnetic field lines.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
What describes resistance to movement to magnetic lines of force?
Resistance to movement of magnetic lines of force is described as reluctance. Reluctance is similar to resistance in an electric circuit and is a measure of the opposition that a magnetic circuit offers to the magnetic flux. It depends on the material and the geometry of the magnetic circuit.
How can produce electromagnetic force?
Electromagnetic force is produced by the interaction of electric charges and magnetic fields. When a charged particle moves through a magnetic field, it experiences a force perpendicular to its velocity and the magnetic field lines. This force is the electromagnetic force.
What is an excellent conductor of magnetic lines of force?
Iron is an excellent conductor of magnetic lines of force due to its high magnetic permeability. This property allows iron to easily attract and retain magnetism, making it a common material used in electromagnets and magnetic cores in transformers and electric motors.
What is the imaginary line that helps us visualise a electric or magnetic field called?
The imaginary line that helps us visualize an electric or magnetic field is called a field line. These lines represent the direction of the force that a positive test charge would experience in the presence of the field.
Which is true of magnetic field lines but not electric firld lines apex?
Magnetic field lines always form closed loops, while electric field lines begin and end on charges. Additionally, magnetic field lines do not originate from monopoles, while electric field lines can begin and end on electric charges.
How it can be possible to produce electric current in a uniform magnetic field?
-- Form a continuous circuit out of a conducting material. -- Move the conductor through the magnetic field, at an angle to the magnetic 'lines of force'.
Where is the magnetic force the greatest on a magnet?
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
What happens when a loop of wire cuts magnetic line of force?
When a loop of wire cuts magnetic lines of force, an electromotive force (EMF) is induced in the wire. This phenomenon is known as electromagnetic induction, and it is the basic principle behind generating electricity in generators and the functioning of electric motors. The induced current in the loop is proportional to the rate at which the magnetic lines of force are cut by the loop.
What is a magnetic field made of and how does it interact with other objects?
A magnetic field is made of invisible lines of force that surround a magnet or electric current. It interacts with other objects by exerting a force on them, either attracting or repelling them depending on their magnetic properties.
