the presence of a magnet
What else can I help you with?
How are magnetic fields and electric current related?
The two are related because an Electric current produces Magnetic Fields
An electric current produces?
Produces magnetic fields, that are used in generators, inductors and motors. The magnetic field at any given point is specified by both a magnitude and a direction.
Only some currents are able to produce magnetic fields?
No. Any current produces a magnetic field. Look at Maxwell's equations.
What produces the sun's magnetic fields?
The sun's magnetic fields are mainly produced by the movement of electrically charged particles within its interior. This process, known as the solar dynamo, generates complex magnetic fields that influence solar activity like sunspots and solar flares.
What device produces magnetism?
A device that produces magnetism is an electromagnet, which generates a magnetic field when an electric current flows through a coil of wire. Other devices include permanent magnets, which are made from materials that have a persistent magnetic field. Additionally, magnetic fields can be produced by certain electrical devices like motors and generators, where the interaction of electric currents and magnetic fields is fundamental to their operation.
Why do we need to orient entire set up in magnetic meridian before performing experiment?
Orienting the setup in the magnetic meridian helps ensure accuracy in experiments involving magnetic fields because it aligns the equipment with the Earth's magnetic field. This alignment reduces interference from external magnetic fields and produces more reliable results.
How does a vibrating electric charge produce an electromagnetic wave?
When an electric charge vibrates, it creates changing electric and magnetic fields. These changing fields propagate through space, creating electromagnetic waves. The oscillating electric field produces a magnetic field, and the changing magnetic field then produces an electric field, thus creating a self-sustaining wave.
When was The Magnetic Fields created?
The Magnetic Fields was created in 1989.
How does an electromagnet utilize the interaction of electric and magnetic fields to generate a magnetic field when an electric current passes through it?
An electromagnet uses the interaction of electric and magnetic fields to create a magnetic field when an electric current flows through it. The electric current produces a magnetic field around the wire, and this field interacts with the magnetic field of the material inside the coil, strengthening the overall magnetic field.
What is a science experiment that demonstrates that magnetic fields cannot be blocked?
Magnetic fields can be blocked. Magnetic fields cannot penetrate a superconductor, and regions can be shielded from magnetic fields using ferromagnetic materials.
What do you need magnetic fields for?
magnetic fields are essential to production of electricity
What can be inferred about magnetic fields and paper?
Paper is not affected by magnetic fields.
