They may also exist independently. Without the electric field, the magnetic field exists in
permanent magnets
and also with current carrying conductor and without magnetic field, electric field exists in charges at rest. So, both the electric and magnetic fields exist without each other.
How can you make a magnetic field without electricity?
No you can have a magnetic field
without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.
Can you have a magnetic field without an electric field?
No you can have a magnetic field without an electric field
. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.
Do electric fields always have magnetic fields?
No you can have a magnetic field without an electric field
. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.
Can a magnetic field be stationary?
Around a permanent magnet or a wire carrying a steady electric current in one direction, the magnetic field is
stationary
and referred to as a magnetostatic field. At any given point its magnitude and direction remain the same.
How can a magnet make an electric field?
Moving magnetic fields pull and push electrons
. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
Can electric field exist without charge?
Q1,Yes,
there can be an electric field at a point with no charge
. But there will be no force from it untill a point with a charge is there. No, there will always be a field with a charge.
Is magnetic or electric force stronger?
An electric force is a force of attraction or repulsion between charged particles, which have unequal numbers of protons and electrons. … Similar to electric charges, opposite poles attract, and like poles repel. The stronger the magnets and the closer together they are,
the stronger the magnetic force between them
.
What is the difference between electric and magnetic fields?
A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the
magnitude of the electric force
at any given point in space. Current is the rate of charge moving past a region.
What is the relationship between electric and magnetic fields?
Electricity and magnetism are two related phenomena produced by the electromagnetic force. Together, they form electromagnetism.
A moving electric charge generates a magnetic field
. A magnetic field induces electric charge movement, producing an electric current.
What creates a magnetic field?
The magnetic field is the area around a magnet that has magnetic force. … When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction.
The force generated by the aligned atoms
creates a magnetic field. The piece of iron has become a magnet.
What charge is a magnetic field?
Magnetic fields may be created with magnetic materials. A magnet has a North and a South Pole. A magnetic field flows from the North to the South Pole in the same way that electric fields flow from positive to
negative charges
. However, once cannot isolate magnetic poles
Do magnetic fields move?
So
do magnetic fields
, but from moving charges, or currents, which are simply a whole bunch of moving charges. In a permanent magnet, the magnetic field comes from the motion of the electrons inside the material, or, more precisely, from something called the electron spin.
Can a magnet power a light bulb?
Unfortunately, however, the current created by moving a magnet over a single wire doesn’t provide enough energy quickly enough to actu- ally light the bulb. To light a bulb, or to power anything else, you need to find a way to generate more power, which is the amount of energy produced in a certain time.
Can magnets generate electricity?
The properties of magnets are
used to make electricity
. Moving magnetic fields pull and push electrons. … Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current.
