Do stronger magnets produce more electricity?
You will get a stronger EMF if you have a stronger magnetic field or make the magnetic field change more quickly because you will have greater flux which will generate greater force on the electrons.
Since electric power is just EMF x current, you also get a bigger power this way..
Can a magnet that has lost its strength be re magnetized?
It is possible to re-magnetize a magnet that has lost its magnetic properties, but as long as the alignment of its internal particles has not been modified for any reason, such as, for example, the exposure of these elements to high temperatures.
Where is a magnet’s force strongest?
The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.
Where is Earth’s magnetic field the strongest?
The magnetic poles of the earth are defined as the location of the strongest vertical magnetic field. This places the magnetic north pole just west of northern Greenland (about N80° W70°) and the magnetic south pole near the coast of Antarctica south of Australia (about S75° E150°), as the following diagram shows.
What happens when you put two negative magnets?
When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. … Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
What is the interaction between two magnets?
Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.
Are 2 magnets stronger than 1?
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
Is the Earth’s core magnetic?
The core of the Earth is also an electromagnet. Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core.
What does a magnetic field tell us about two magnets placed side by side?
Two bar magnets side by side but with their fields perpendicular to each other. … This shows the magnetic field strength around these two magnets. It is zero at the bottom between the two magnets, where the fields circulate around from one to the other.
Where is the magnetic field the weakest?
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.
What shape of magnet is strongest?
horseshoe shapeIt is made by bending a regular bar magnet into a horseshoe shape. The strongest part of a magnet is concentrated at the poles. That is why a horseshoe shape is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.
