What else can I help you with?
What is switch called that rotates with an electromagnet?
A rotary switch.
Generator consisting of a coil that rotates between the poles of an electromagnet?
dynamo
Where is the reversing light switch on a Toyota avensis?
How do I get to the reversing light switch on a Toyota avensis 2005
What happens when the electric current is reversed on am electromagnet?
When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
What does the switch do to the electro magnet?
The switch is turned on to activate the electromagnet, and metal is attracted. Turning off the switch stops the electromagnet from working, and metal is no longer attracted.
What happens if you reverse the current flow in an electromagnet?
Reversing the current flow in an electromagnet changes the direction of the magnetic field it produces. This can be useful for changing the polarity of the electromagnet or controlling the direction of a mechanical system it is used in.
What is a reversing switch that rotates with the coil in am electric motor and reverses the direction of the current every half turn?
It's called a 'split-ring commutator'. It changes the naturally-produced a.c. into d.c.
What is the function of the switch in the electromagnet crane?
The switch in the electromagnet crane controls the flow of electric current to the electromagnet. It allows the operator to turn the magnet on and off, enabling them to pick up and release loads.
How is electromagnet used in a burglar alarm?
An electromagnet is used in a burglar alarm to create a magnetic contact switch. When the door or window is closed, the electromagnet keeps the switch closed. If the door or window is opened, the magnetic field is disrupted, causing the switch to open and trigger the alarm.
What is a Generator consisting of a coil that rotates between the electromagnet causing a current to flow in the armature?
dynamo
What is a device with an electromagnet that continually rotates because of a changing electric current?
The device is known as a "motor".
