You are given a material which produces no initial magnetic field when in free space. When it is placed in a region of uniform magnetic field, the material produces an additional internal magnetic field parallel to the original field. However, this induced magnetic field disappears when the external field is removed.What type of magnetism does this material exhibit? diamagnetism paramagnetism ferromagnetism Part BOnce again, you are given an unknown material that initially generates no magnetic field. When this material is placed in a magnetic field, it produces a strong internal magnetic field, parallel to the external magnetic field. This field is found to remain even after the external magnetic field is removed.Your material is which of the following? diamagnetic paramagnetic ferromagnetic Part CWhat type of magnetism is characteristic of most materials? ferromagnetism paramagnetism diamagnetism no magnetism
A is paramagnetic B is ferromagnetic (strongly magnetic, adds greatly to magnetic field) C is diamagnetic (weakly opposes external magnetic field)
its not advisable to use copper underground. I would use copper inside your house and plastic under ground anyway with the products on the market now plastic is so much easier to install make sure you buy a proper plastic pipe cutter and fit the inserts and you wont go wrong another good tip is marking the pipe so you know you have pushed the fitting fully home
For the best answers, search on this site shorturl.im/aw86g Yes.Table Y,plastic coated,annealed copper can be used under ground. The pipe you buy from the likes of BQ cannot.
Yes the newest modern metal detectors have controls that will allow you to pick the type of metal you want to detect. And also how deep you want it to check for that metal. You can set them for iron, gold, silver, copper or lead. You can even tell them what metals to ignore such as aluminum. They are very sophisticated now.
