How do you make electricity using magnets?
Any wire carrying an electric current has a small magnetic field shaped like a corkscrew around it. Winding many coils of wire on a bobbin or tube will greatly increase the magnetic field and this is called a solenoid. If you connect the two ends of the solenoid to a battery it becomes an electromagnet. Placing a soft iron rod inside the bobbin will concentrate the magnetic field making it possible to pick up small iron and steel objects. Break the electric current in the coil and the magnetic field disappears leaving only a small remnant field in the steel rod. The strength of the electromagnet depends on the number of coils in the solenoid and the size of the current flowing through it.
How much current does an iPad 2 draw to charge the battery?
This will be marked on the label on the iPad and its original charger.
Can magnetic field lines be detected by a compass?
The magnetic field can certainly be detected by a compass.The 'lines' are a handy human invention, and don't really exist, so you could not,say, trace out the lines with a compass, because they're not there.But place a compass next to a wire that's involved in any battery-operated (DC)circuit, and the compass absolutely goes crazy !
What is a sentence with battery?
Battery can have several meanings, I will try to cover some of them with different example sentences...1. Because I left the lights to my car on, my car battery was drained of power, and thus my car would no longer start.2. After I punched the man in the face, I was taken to jail by the police and charged with battery.3. Before we sent the ground troops over the border, we opened with with the artillery battery to weaken the strength of our opponents forces.4. When I arrived late to the Metallica concert, I was disappointed to find out that they had already played the song Battery.
How much battery power would it take to power an electromagnet?
Any strength of power source can be used to make an electromagnet. A single AA battery, used well, can (at least briefly) power an electromagnet that can hold several pounds of metal in the air. An electromagnet's strength is determined by three factors: * the material in the core (air makes a weak magnet; iron a reasonably strong one) * the amount of current in the wire * the number of turns that the wire makes around the core The strength of an electromagnet is often referred to in "amp-turns": the number of turns times the amount of current it has. A simple battery approximates a voltage source: that AA battery pushes out about 1.5V of electricity. Divide that 1.5V by the resistance of the wire (longer wire higher resistance) and you get the current in the wire. At least, until your voltage source gives up and can't deliver that much current any more--then you need a new battery. :)
Which change will most likely increase the strength of a magnetic field produced by an electromagnet?
Add a battery
What factors may affect the strength of the magnetic field generated around the coil?
Number of loops and Battery voltage
What factors may affect the strength of the magnetic field generated around a coil?
Number of loops and Battery voltage
Will a lead-acid battery function after an Electro Magnetic Pulse has been applied?
Depends on the strength of the pulse. A strong pulse could cause the complete discharge of a battery.
Can a battery have a magnetic charge?
No the battery don't have a magnetic charge.
How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
Is a battery magnetic?
no
How do you increase current in a battery?
we can increase the current in battery by using current amplifiers or chopper's s the easy way to increase the current in battery........
What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?
The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
Cheap Original dell inspiron 1100 battery?
Original dell inspiron 1100 battery you can search it at Dell.com I suggest you can choose a replacement battery, replacement battery has the same performance, and replacement battery is cheaper than original.
