What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
What happens when a coil of wire cuts through a magnetic field?
If the magnetic field is fluctuating, or the coil of wire and magnetic field are moving with respect to each other, then a current is induced in the coil of wire. If the two are stationary and the magnetic field is stable, then no current is induced in the coil. However, if there is a current in the coil, from another source, then the coil and the field will exhibit a relative force that will tend to move the coil with respect to the field.
What happens when the current in the coil is halved?
What happens when the current in the coil is halved? No pins are attracted. ... A magnetic field is always created around a wire when it carries electric current.
What is transformer turns ratio excitation current?
This is the current level needed to energize a transformer to its rated voltageThe clue is in the name! 'Excitation' means to create a magnetic field. So the excitation current is the current drawn from the supply which sets up the magnetic field around the core.
What happens When a wire with a current is placed in a magnetic field?
electricity is induced
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
In an electromagnet as the electric current changes what happens to the magnetic field?
the magnetic field would constantly change, that's why the AC current is converted to DC current
What happens to the magnetic field of wire when you change the direction of a current of the wire?
In that case, the magnetic field will also be reverted.
What happens when an electric field is placed inside a magnetic field?
Electricity is formed (electrons move )
Which happens to the magnetic field of a wire when you change the direction of the current in the wire?
The polarity of the magnetic field of a wire reverses when you change the direction of the current in the wire.
When is the force experienced by a current carrying conductor placed in a magnetic field the largest?
When the conductor,magnetic field and motion are perpendicular to each other
What happens when a compass is placed near a current-carrying wire?
That depends. If we assume that current is flowing though the wire then there is an induced magnetic field equal to B=u_o*I/(2R*pi). For a visual refer to http://hyperphysics.phy-astr.gsu.edu/HBASE/magnetic/magcur.html#c2
