What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
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 when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
Name two devices which use current carrying conductor and magnetic field?
One device for increasing the magnetic field surrounding a current carrying wire, is to wrap the conductor into a set of co-axial coils. A second device is to include a ferromagnetic material in the core of such a coil.
For a current carrying coil if the current is doubled then the field strength is?
doubled
What is the cause of a magnetic field about a current-carrying wire?
The cause is the current.
What is a coil of wire that when carrying a electric current produces a magnetic field?
No field
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
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.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
In a current carrying conductor what exist around it?
a magnetic field
Does coil of wire carrying a current have a magnetic field?
yes
What happens when you reverse the current in a current-carrying magnetic field?
The polarity of the electromagnet reverses.
What form around a wire carrying an electric current?
Electromagnetic fields form around any current carrying conductor.
If a conductor carrying an alternating current is formed into a coil the magnetic field that is generated?
If the current is alternating, the magnetic field will also be alternating.
Energy is a current carrying coil is stored in the form of?
electric field
