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.
Where is the magnetic force the weakest?
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
Where are magnetic forces strongest?
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are least dense at the center and densest between the two poles just outside the bar magnet.
What makes magnetic force stronger or weaker?
The magnetic field magnitude is proportional to the density of the lines. The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.
Which is stronger electric force or magnetic force?
The one created by electric field is independent form particle velocity, while the Lorentz force is proportional to particle velocity. Thus at v=0 the electric part of force acting on particle is infinitely stronger than magnetic part.
Where is the magnetic field the strongest and why?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)
What are the strong and weak forces?
The strong nuclear force pulled positively and negatively charged quarks together to form positively charged protons and neutrally charged neutrons. The strong nuclear force also binds protons and neutrons in the nucleus of atoms. The weak nuclear force enabled complex atoms to form through nuclear fusion.
How strong is magnetic force?
Magnetic fields that surpass about a billion Gauss are so strong that they compress atoms to tiny needles, destroying the ordinary chemical bonds that bind atoms into molecules, and making chemistry as we know it impossible.
Is the region where the magnetic field of a magnet is strongest?
The poles are regions where the magnet is strongest. The poles are called north and south because they always line up with Earth’s north-south axis if the magnet is allowed to move freely.
Where is the strongest magnetic field in a coil?
You can create a stronger magnetic field by taking wire and forming it into a coil; the field is more concentrated in the center of the loop than outside the loop. By adding more loops to a coil, you create an increasingly stronger magnetic field.
Does electricity make magnets stronger?
When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak. … There is another way that uses electricity to make a temporary magnet, called an electromagnet.
What determines magnetic strength?
The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets ‘strength’. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.
What affects the strength of magnetic forces?
Explanation: The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. … North and south poles of magnets are attracted to each other.
