What else can I help you with?
Does a LCD TV have electromagnetic field?
Yes, any device that uses power will have a electromagnet field though it might be small.
What protects earth from most solar wind?
Its the magnetic field of the Earth that protects us from the solar wind. This deflects the stream of charged particles away from us, creating the magnetosphere.
What is a electromagnetic sensor?
An electromagnetic sensor is a device that detects or measures electromagnetic fields or waves. These sensors can be used for various purposes such as detecting metal objects in proximity sensors or measuring the magnetic field strength in compasses.
When electric and magnetic fields both exist it is called an?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
How can you make an electromagnetic device?
To make an electromagnetic device, you will need a power source such as a battery, a coil of wire to create a magnetic field, and a core material like iron to enhance the magnetic field. By passing an electric current through the coil, you can create a magnetic field, which can then be used for various applications such as electromagnets, generators, or electric motors.
What device is used for electromagnetic radiation?
Electromagnetic radiation is just light. You can measure light with a light meter, which tells you intensity, or a camera sensitive to different frequencies. You can also use a magnetometer (Gaussmeter) to measure the B field component or a voltmeter to measure the E field component.
Which layer of the Earth protects agains metiors?
The Earth's atmosphere is the layer that protects against most meteoroids by burning them up as they enter. Additionally, the Earth's magnetic field deflects charged particles from the Sun, which can also help protect the planet from space debris.
What is a device for generating or amplifying microwaves?
A magnetron is a device commonly used for generating microwaves in microwave ovens. It works by utilizing the interaction of electrons with a magnetic field to produce electromagnetic waves at microwave frequencies.
What determines the direction of polarization of a radiated electromagnetic field?
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
What are facts about electromagnetic fields?
An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.
What is a field circuit?
A field circuit is an electrical circuit that supplies current to the field windings of an electromagnetic device, such as a motor or generator. It is responsible for creating the magnetic field necessary for the operation of the device. In motors, the field circuit can influence the speed and torque, while in generators, it affects the voltage output. Typically, field circuits can be either series, shunt, or compound, depending on how they are configured with respect to the armature circuit.
A sentence with the word electromagnetic?
The scientists measured the electromagnetic field.
