In 21 dares do you do 4 numbers or 3?
you have three turns each
What do the numbers for a screw mean?
length of the screw, and number of turns per inch
How do you find the reciprical?
You just flip the numbers of the fraction.....such as 1/7 turns into 7/1...
Why do the iron nail attracts more number of pin when wrapped with a cool of more number turns?
Wrapping a number of coils of insulated wire around an iron nail, and a passing a current from a battery through it, turns the iron nail in to an electro-magnet. While the current flows, the nail will attract metal objects. It is a standard demonstaration in science classes in schools. The more turns the stronger the attraction.
What is the formula to calculate pitch of a hexagonal nut?
For metric, use mm - For English, use Inches English Example: [ 1inch / (thickness of nut) ] x (number of turns for the bolt to get through the nut ) typical numbers are 18, 24, and 32. Metric: (thickness of nut in mm) / (number of turns for the bolt to get through the nut) typical numbers are 1, 1.25, 1.5, and 2.
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.
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. :)
What in an electromagnet the what turns the drive shaft which does the work?
the armature
How does the number of wraps of wire affect the strength of an electromagnet?
The more turns of wire in an electromagnet the stronger the magnetic field.
The device that turns a needle in a galvanometer is called an electromagnet?
True.
In an electromagnet what turns the drive shaft that does the work?
An iron or steel with wire wound on it turns the drive shaft.
What is stronger an electromagnet with 20V and 5A or one with 5V and 20A?
The strength of an electromagnet depends on the current through the coil andthe number of turns in the coil. The voltage across the coil doesn't matter at all.So IF both of your electromagnets have the same number of turns in their coils,then the one with 20A of current is stronger than the one with 5A of current.If they have different numbers of turns in their coils, then we need more informationbefore we can decide which one is stronger.
True or false The device that turns a needle in a galvanometer is called an electromagnet.?
true
Does making the core of an electromagnet larger make it weaker?
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
How do you make an electromagnet with a rivet and a wire?
Wrap the wire around the rivet as many times as you can, and connect the ends of the wire to a battery.Turning on the electricity turns on the electromagnet. More turns of wire means a stronger magnet.See also related Wikipedia link.
Who invented the first electromagnet motor?
British scientist William Sturgeon invented the electromagnet in 1824.[7][8] His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
