How Do Copper Wires Wrap Around The Nail Affect The Strength Of The Magnet

The objective of this experiment was to calculate the percentage of copper in three random pennies by applying

Used stirring rods to completely remove copper from that wire. And then completed the removal of copper using 5 drops of 6M HCl, adding it onto copper. There will produced copper in a solution. Connected Buchner flask to the vacuum line and place filter paper in it to completely washed off the copper. Then, add 95% ethanol to copper and leave it for 1 min and turned section back for 5 mins. Measured mass of clean, dry watch glass. Transfer copper to watch glass and dry it under heat lamp for 20 mins, allowed it to cool to room temperature and then accurately determine its mass.

Then I attached the black clip to the coin and the red clip to the copper strip. I then placed each item in the copper sulfate solution and attached the opposite end of the black clip to the negative side and the red clip to the positive side of the battery. Then I waited ten minutes to observe the effects on the items. I then re-cleaned both items and followed the above steps, except the clips. I placed the red clip on the negative side and the black clip on the positive side of the battery. I performed this experiment with the coin and copper strip first and then re-performed the same experiment with the key and copper

Refer to the reaction of iron nails with a copper solution assignment in Module 3, Section assignment 3.4 Part F of the Chemistry 11 course.

The magnetic field rotates 180 degrees when the battery slider moves from one side of the battery to the other.

Discussion: The main scientific concept explored in this laboratory was the ability to observe the chemical reaction between Fe and Cu and to determine the ratio of moles of iron used to moles of copper produced in the reaction. A chemical reaction occurred when we used 4.06 grams of copper (II) chloride and mixed it with 9.43 grams of iron nails. The copper (II) chloride used 1.24 grams of iron from the nails to produce 1.99 grams of copper solid.

The fabrics that I am using are, a polyester blanket, my long hair and a cotton sweatshirt. Polyester tends to gain a negative charge and attract electrons. Human hair tends to give up electrons and gain a positive charge. I am also using a cotton sweatshirt and

When you want to working a nail gun, it is very chief things that you know how to use it properly in order to negate the possibility of injury and even death. Here are some simple steps that can be used when operating nail guns to ensure that everything runs smoothly.

2. Carefully straighten the steel paper clip. Use the wire clippers to cut it to the same length as your copper wire.

A magnet can be created by putting a magnet in contact with material such as iron, nickel and aluminum. Magnets can be classified as permanent magnets or ferromagnetic magnets. Permanent magnets are rare earth magnets that have a high

More thought could’ve been done when first conducting the experiment. A strategy that could have been implemented could have been the installation of insulation to the copper tin to reduce the amount of heat that escapes.

True or False: A permanent magnet is a piece of material that has been magnetized and can hold its magnetic strength for a reasonable length of time. True.

Magnetic repulsion works on the principle of using electro magnets to levitate objects. Unlike normal magnets, electro magnets are created by the movement of current through wires. This means that the strength of the magnet can be changed by increasing or decreasing the current in the wire. As well as this, it is possible to change the poles of the magnet. This is important as it allows the magnet to both push and pull depending on the current. Using the idea that north repels north and south repels south, if the ground were to have the same pole as the electric magnet, then the electric magnet would hover. This idea can better be seen in figure 1.

An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:
