How can magnetic field be produced without using magnet?
Yes,it can be produced.
A moving charge can produce magnetic field.
An electric conductor carrying current can produce magnetic field.
A coil,solenoid,toroid can also produce magnetic field..
Does a magnet produce a magnetic field?
The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. … When electricity runs through a coil of wire, it produces a magnetic field.
Can you generate electricity without magnets?
Well, photovoltaic panels are sometimes considered generators. It’s also possible to make electrostatic generators that have no magnets or electromagnets at all. For example a Wimshurst machine. Electrostatic generators do work, but they’re not usually very powerful, although they can generate high voltages.
What will happen if there is no magnetic field?
Satellites can and do suffer damage from solar storms, and without Earth’s magnetic field, every electronic device could be exposed to high-energy particles from cosmic rays and the solar wind. … If Earth lost its magnetic field, there would be no magnetosphere – and no line of defense, even from weaker solar storms.
How do you create a magnetic field?
A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside.
What are the properties of magnetic line of force?
General Properties of Magnetic Lines of ForceThey seek the path of least resistance between opposite magnetic poles. … They never cross one another.They all have the same strength.Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.More items…
