talking about electric and magnetic forces and those are just some really cool tricks that you can do with really super powerful magnet try out later on this week if we get through all the time so let's get started first of all when you talk about electric and for since you have to start with Adams take an electric and magnetic forces exist because there are times and we've talked about this before proton has a positive charge while electrons have a negative charge so if you look at the atom here here is the electron carrier proton and just a quick review of the other part of the new neutrons have no charge if the number of protons and electrons for each other app please electrons very very easily through which we called they are straining electrons adding extra negative things that you'll have a slightly negative when you breathe easy, because it's Adams now positive I'll be attracted and Banton negative charge because Opposites Attract an electron it is slightly positive so it will be attracted to some things that we need to keep in mind or our basic four forces of nature first of all are magnetic forces this is the attractive and repulsive forces between two poles stove when you look at a magnet North Pole opposites North and North will repel North and South will electric forces occur ions create attractive and repulsive forces and these two forces can work together or independently electromagnets magnetism is kind of combination of two it's a force check and magnetic forces so all matter is made of atoms Natalie charged electrons spin around stats there's electrons they just the electron clouds around I are around the nucleus where electrons all spin in the same direction that can create an invisible force known as the power of a magnet is the magnetic force of that magnet magnet to get into pole North and South poles come close to take me to attract or repel when I filled the stronger the magnetic field this man is under the paper and iron filings detect the normal invisible lines of the magnetic field of the magnet status in lab later on this electric forces electric charges create electric forces attract or repel this is called static electricity which does not move through a current or circuit are you remove electrons has a negative charge to those balloons there's extra electrons with them now your hair has gotten those electrons will be electrically attracted what causes it to stand on end electric current and we can measure these but it's the rate of flow of charged particles and needs electric charge is made up of protons and electrons Onslow in a circuit current is produced and it so I can eat it hopefully measuring the we will definitely be making an electromagnet and again remember electromagnet is a combination of the two the electric charges in both create a magnetic field an electric current is moving a charge and a current flowing through the wire is surrounded by magnetic field this produces an electromagnet so you have electricity going through magnetic field circling electromagnetism is when you came in. rapper wire around a piece of iron or steel to make a magnet stronger and when you do this increase in the number of Loops of the wire and increase voltage so again this week some uses of electromagnets magnetism change by changing the amount of electric current that flows through it again in your refrigerator these electromagnet turn on and off the electricity but some uses are hard drives speakers Motors generators MRI machines scrap yard magnets to pick up heavy metal and that's it so make sure you do a good job with these you are going to use this now on a little assessment so what you need to do now is you need to go to schoology to take the number use your notes so what I want you to do go to schoology take that assessment number one using these notes and then as soon as you're done you're going to glue teeth and cheek
