An electro-magnet can be turned on and off.
Load shedding is what happens when electric companies deliberately cut some of their customers' power off to reduce the demand on the system. The result is sometimes called rolling blackouts, as the area cut off from power is often switched from one part of the grid to another. It is a way of managing extreme demands on power that the power company is unable to satisfy.
Italia was one of dem.
industrial
One effect was that it switched peoples daily program and that caused a lot of conflict
Italy hasn't used lira since 2002 when they switched to the euro. At that time 100 lira was worth about 7 US cents.
An electromagnet. Unlike other magnets it can be switched on and off.
An electromagnet can - for example in scrapyards where a crane picks up a car with power on, then drops it when power switched off.
A horseshoe electromagnet is an example of a temporary magnet because it only exhibits magnetic properties when an electric current is passed through it. When the current is turned off, the magnetism disappears.
When the electric current is switched off, the electromagnet loses its magnetic field, causing the metal material to no longer be attracted to the magnet. This results in the metal dropping off from the electromagnet due to the absence of the magnetic force that was previously holding it in place.
The electromagnetic crane has a huge electric magnet that is operated by an electrical current. When the electricity is switched on the magnet becomes magnetized for allowing metal objects to be picked up just like an ordinary magnet, but when electricity is turned off the metal object fall away.
Someone switched off the light.
An electromagnet only retains major magnetic properties when a current is being run through it.AnswerWhether a material makes a permanent or temporary magnet depends on the nature of the ferromagnetic material involved. For example a coil with a steel core will retain much of its magnetic flux density when the current is switched off, whereas a coil with an iron core will lose most of its magnetic flux density when the current is switched off.
switched-off i believe
electromagnetic crane has a huge electic magnet instaed of a hook. this magnet is operated by an electrical current. when electric is switched on the magnet becomes magnetized,allowing metal objects to be picked up just like an ordinary magnet.when elctric is turned off the metal object will fall away, as it is no longer magnetized.
the information is lost after power is switched off.
because operating system is on while phone is switched off
subaru legacy engine is switched off when stop after drive
