Understand what a magnetic field is. Learn the definition of magnetic field lines and understand how one can detect magnetic field lines using a compass. Related to this Question What is magnetic field strength? What is a static magnetic field?
What is a magnetic field?Question:What is a magnetic field?Magnetic FieldA magnet is an object with a force of attraction for other ferromagnetic materials. The force is created as there is a flow of charges from one pole to another. The earth emits a magnetic field that helps deflect sol...
A magnetometer is a tool or instrument that measures the magnetization of an item or the force of a magnet. The magnetometer typically looks at the Earth’s magnetic field and local magnetic field in order to determine the location and vector of a magnetic force. Advertisements Techopedia Expla...
Magnetic tape is one of the oldest technologies for electronic data storage. While tape has largely been displaced as a primary andbackup storagemedium, it remains well suited for archiving because of its high capacity, low cost and long durability. ...
A semiconductor is a substance that can act as a conductor or insulator depending on other factors, enabling it to serve as a foundation for computers and other electronic devices. The term semiconductor is now widely associated with integrated circuits. ...
all matter is magnetic to some degree because electrons orbiting an atomic nucleus produce a magnetic field. In the presence of an electric field, atoms and molecules form electric dipoles, with positive-charged nuclei moving a tiny bit in the direction of the field and negative-charged electrons...
An electromagnetic field (EMF) is an electricity derivative produced by electrical conductors and alternating currents. EMFs surround electronic devices when there is a change in charged particle velocity. Electrical currents are generated and ignite magnetic fields that are produced when charged electrons...
