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?
The strength of an electromagnet is directly proportional to the number of turns in the coil. Increasing the number of turns in the coil increases the magnetic field strength produced by the electromagnet.
What can affect the strength of an electromagnet?
Factors such as the number of turns in the coil, the amount of current flowing through the coil, the material of the core inside the coil, and the presence of any ferromagnetic materials nearby can affect the strength of an electromagnet. Additionally, the size and shape of the coil, as well as the distance between the coil and the object being attracted, can also impact the magnet's strength.
Does the number of turns of wire make a difference to the strength of the electromagnet?
Yes, the number of turns of wire in an electromagnet affects its strength. More turns of wire create a stronger magnetic field because it increases the flow of current, resulting in a more powerful electromagnet.
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. :)
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.
What is stronger an electromagnet with 20V and 5A or one with 5V and 20A?
The strength of an electromagnet is determined by the product of voltage and current. Therefore, the first electromagnet (20V x 5A = 100) would be stronger than the second electromagnet (5V x 20A = 100) because they both have the same power output.
What happened to the strength of the electromagnet when more turns of wire were used?
The strength of the electromagnet increases when more turns of wire are used because higher number of turns result in stronger magnetic fields produced by the current flowing through the wire. This strengthens the attraction of the electromagnet to magnetic materials.
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 the strength of an electromagnet proportional to?
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.
How does the number of turns affect the strength of the electromagnet?
The number of turns in the coil of an electromagnet affects its strength. More turns generally result in a stronger magnetic field because each turn contributes to the overall magnetic flux. Increasing the number of turns increases the magnetic field intensity and thus the strength of the electromagnet.
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.
