IEDs consist of conventional military ammunition or bombs but are normally designed from non-military components. According to bomb experts in the Kenya Army Corps of Engineers, an IED has four ...

Magnetic chucks use the magnetic force from a permanent magnet, electromagnet, or electro-permanent magnetic material to achieve chucking or holding action. In recent years, magnets have increased in ...

Magnetic couplings are non-contact couplings that use a magnetic field to transfer torque, force or movement from one rotating member to another. The transfer takes place through a non-magnetic ...

Magnetic resonance imaging (MRI) is a non-invasive biomedical imaging technique that uses a strong oscillating magnetic field to induce endogenous atoms such as hydrogen, or exogenously added ...

If a magnet is moving near to a wire it will generate an electric current and if an electric current is moving through a metal it can make a magnetic field. This is called an electromagnet.

Wonder material graphene can be made magnetic and its magnetism switched on and off at the press of a button, opening a new avenue towards electronics with very low energy consumption. This is the ...

Officials reported a significant breakthrough on Wednesday, as they discovered three improvised explosive devices (IEDs) at a terrorist hideout in the border district of Poonch. The IEDs, weighing ...

But what does this mean - and haven't compasses always pointed 'north'? Erika Jones, curator of Navigation at Royal Museums Greenwich, helped explain this rare occurrence, and the difference between ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

Three improvised explosive devices (IEDs) were seized from a suspected terrorist hideout in the border district of Jammu and Kashmir's Poonch ahead of the upcoming Lok Sabha polls. The operation ...
