Q: isn,t there some way to do it with electricity,safely!: Take the sheet and and roll it with paper between it .Then take a long copper wire without the plastic covering and round it along the entire sheet evenly in one direction( clock or anticlockwise direction).wound it a number of times till it becomes a big coil.Then connect the end you started from (if clockwise ) to the +ve terminal of a D.C power supply(if anticlockwise then follow the reverse) and obviously the other end to the -ve.(remember directions).After completing the circuit let the current of high voltage (10-15 volts) pass through the coil for a few hours.If everything done properly you end up having a very strong permanent magnet.

Q: i already know some but i really wanted to ask if pens are allowed inside the plane. i want to bring ballpens and pencils inside the plane.the pencils are not that sharp but they are sharpened. it‘s really confusing so i don‘t know if i will bring them or not.: i've heard of it but can't say who exactly. maybe vw, or saab, or even volvo. they are cold countries where they are designed.

Q: If you know the current? Magnetic fields confuse me a bit in general and I‘ve googled this numerous times and haven‘t been able to find a simple answer. Please help!: Solenoid Magnetic Field Calculator

Q: Which type of magnetic material would you choose To use as a shield for a meter movement? The shield is to short-circuit the flux around the movement.1) paramagnetic2) diamagnetic3 ferromagnetic: An 8-bit virtual item that has little to no use to you in real life.

Q: how does the circuit in the machine work?what materials can a scrap heap magnet moove?what materials can‘t a scrap heap magnet moove?: The circuit is just a solenoid (coil of wire) connected to a power supply. It works because when current flows through a wire, a magnetic field is induced. It can lift any magnetic material, mainly ferrous objects, but also some other metals.

Q: I am building out some office space. I‘d like to have a roughly 12 ft. by 8 ft. high wall that is magnetized such that I can hang large maps. I‘d like to paint it if possible, so when maps are not there, it basically looks like a regular wall. What is the most economical way to do this?: They have magnetic paint and primer. I hear the magnetism can fade though. Could see about a magnetic whiteboard or chalkboard. Though it obviously wouldn't look like a regular painted wall.

Q: how we analyse the magnetic strength using some meters or instruments. explain?then we doing one project, there i mating two magnets in repulsive position(ie N-N or S-S) under some force. but magnets are constrained not to move from its linerepulsive force. what will happen? when the magnetic field strength is equal to applied load. then what will happen to magnet material? it may break or not.?or explain me when will magnet may break due to its own magnetic power: Read about motor induction and EMF It's fascinating.

Q: Lines of force do what ?A)are created by electricity onlyB)repelC)never crossD)cancel out magnets: 1. Magnetic lines of force are continuous and will always form closed loops. 2. Magnetic lines of force will never cross one another. (c) 3. Parallel magnetic lines of force traveling in the same direction repel one another. Parallel magnetic lines of force traveling in opposite directions tend to unite with each other and form into single lines traveling in a direction determined by the magnetic poles creating the lines of force. (B) 4. Magnetic lines of force tend to shorten themselves. Therefore, the magnetic lines of force existing between two unlike poles cause the poles to be pulled together. 5. Magnetic lines of force pass through all materials, both magnetic and nonmagnetic. 6. Magnetic lines of force always enter or leave a magnetic material at right angles to the surface. B and C

Q: Why does the poles of a Magnet are changed if it is broken?: bcoz when a magnet is broken into pieces, each broken magnet pieces serve as individual magnets. and so they have individual polarity. hence, the polarity changes.

Q: Hello.We‘re measuring the thickness of an organic coating on carbon steel and we have two probes: one works by magnetic induction, one by the eddy current method. They‘re both right-angle probes designed to measure the inner coating of pipes.When testing on a flat sheet of stainless steel, both probes give accurate measurements. But when tested on a carbon steel cylindrical pipe, the eddy current probe is way off (reading 667 um when put right against the metal)!We will be using the ‘proper‘ probe, but still I‘d like to know how the eddy current probe behaved in such a way. Is it because of the geometry (flat sheet vs. pipe)? I suppose eddy currents would take different paths.I‘m not an engineer as you will have guessed.Also, I know NF/FE means ferrous metals and NC/NF means nonferrous, but what do these acronyms mean exactly?: I've used ultrasonic testing, not eddy current or magnetic induction. However, no one has answered so I'll take a stab at it. I expect two issues: magnetism and calibration. Materials that are strongly magnetic are called ferromagnetic, while those that don't are called non-magnetic. Stainless can be either ferromagnetic or not, depending on the crystaline structure, i.e. type of stainless and (sometimes) heat treat condition. Could it be that the magnetic properties of the underlying material affects the readings? More specifically, do both methods work with both magnetic and non-magnetic materials. Second issue is calibration. If you calibrate for steel, maybe calibration not valid for stainless, or vice versa. Round or flat should not make much difference. Good luck!
