What are the Advantages of using NDT? There are a number of distinct advantages, the most obvious of which is that thepieces being tested are left undamagedby the process, allowing for an item to be repaired rather than replaced should any problems be found. ...
A different category of magnets are electromagnets, which are essentially magnets that can be turned on and off. The most common electromagnet that is used in various industrial applications is a solenoid. A solenoid is a series of current loops, which result in a uniform field in the...
Traditional speakers produce sound by using an electromagnet to move a flexible cone back and forth. They use drivers to help translate electrical signals into physical vibrations so that you can hear recorded sounds. A tweeter is the type of speaker driver that produces the highest range ...
In a typical DC motor, there are permanent magnets on the outside and a spinning armature on the inside. The permanent magnets are stationary, so they are called the stator. The armature rotates, so it is called the rotor. The armature contains an electromagnet. When you run electricity ...
It becomes magnetized only when an electric current is passed through the coil. Electromagnet brushed DC motors generate their magnetic flux with the electromagnet. Electromagnet motors are classified into three types: shunt motors, series motors, or separately excited motors, depending on the ...
These MCBs combine a bimetallic strip and an electromagnet to provide both thermal and magnetic protection. The bimetallic strip responds to the average current over time, while the electromagnet responds to the peak current in case of a short circuit. ...
