What does magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
Do circuits or electric currents have a magnetic field?
Yes, electric currents generate magnetic fields. This is described by Ampere's law in electromagnetism, stating that a current-carrying conductor produces a magnetic field around it. This relationship between electric currents and magnetic fields is fundamental to the operation of electromagnets and many electronic devices.
Are permanent magnets produced by electric currents?
No, permanent magnets are not produced by electric currents. They are made from materials that are magnetized and retain their magnetic properties without the need for external electric currents.
What causes magnetic fields?
It is caused by moving electric currents>
Definition of electromagnetic wave magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
What is the definition for magnetic field relating to normal and reversed?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
What is the simple definition and concept and application of magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
Do magnets affect electric?
Yes, magnets can affect electric currents and vice versa. Moving electric charges create magnetic fields, and magnetic fields can induce electric currents in conductors. This relationship is fundamental to electromagnetism and is used in many technologies, such as electric motors and generators.
How do magnets magnetic fields electric currents and metals connect?
Magnets produce magnetic fields which can interact with electric currents to generate forces or induce currents in the conductive materials like metals. When an electric current flows through a metal conductor, a magnetic field is produced around it. This interaction forms the basis of electromagnetism and is used in various applications such as electric motors and generators.
How does the interaction of magnetic fields and electric currents contribute to what makes a magnet work?
The interaction of magnetic fields and electric currents creates a magnetic force that aligns the atoms in a material, making it magnetic. This alignment allows the material to attract or repel other magnets, which is what makes a magnet work.
What is the difference between magnetic and electromagnetic fields?
Magnetic fields are created by permanent magnets or electric currents, while electromagnetic fields are created by electric currents. Electromagnetic fields are more complex and can change over time, while magnetic fields are static.
What does a magnetoencephalography do?
It measures the magnetic fields produced by nerve cells and their electric currents
