What are two factors that affect the strength of magnetic forces?
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.
What is the force of attraction between two magnets?
The force that a magnet exerts on certain materials, including other magnets, is called magnetic force. The force is exerted over a distance and includes forces of attraction and repulsion. North and south poles of two magnets attract each other, while two north poles or two south poles repel each other.
What factors affect magnetic and electric force?
The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.
What determines whether two magnets will be influenced by attractive or repulsive magnetic forces?
It is repulsive if the currents are in opposite directions. Two circular current loops, located one above the other and with their planes parallel, will attract if the currents are in the same directions and will repel if the currents are in opposite directions.
What causes magnetic attraction?
Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. … Their movement generates an electric current and causes each electron to act like a microscopic magnet.
What causes magnetic attraction and repulsion?
Inside the iron bar are tiny magnetic regions called domains. When a strong magnet is present, these domains line up with most of the north seeking ends in the same direction. … When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion.
Where is the force of attraction the strongest on a magnet?
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
How are magnetic forces?
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. … The magnetic force on a moving charge is exerted in a direction at a right angle to the plane formed by the direction of its velocity and the direction of the surrounding magnetic field.
What factors affect electric force?
The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.
How is magnetic force like electric force?
Electric and magnetic forces are non-contact forces, which means objects exerting these forces on each other don’t need to be touching. The two types of forces are related; a moving magnet can make electrical charges move, cause an electric current, and in turn cause magnetism.
What is the effect on the force of attraction between two magnets as the distance between them changes?
What happens to the force of attraction between two magnets as the distance between them changes? The force of attraction decreases as the magnets get farther apart.
Why does the magnetic force change when you add more magnets?
By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.
What is the force of attraction or repulsion of magnetic materials?
The force of attraction or repulsion of magnetic materials.
