Is a coin a magnetic material?
a coin maybe magnetic but there are coins that are magnetic and others are not for example a coin coated with GOLD IS NOT MAGNETIC BUT ONE THAT HAS IRON IS MAGNETIC .More answers from other pages
What containers are recommended for waterproof storage?
Waterproof storage containers are typically made out of plastic or coated with a waterproof material. A container that is recommended is the Rubbermaid waterproof storage box.

Explain the working principle of the hard disk drive?
A hard disk uses platters, round discs that are coated with a special media that is designed to store data in magnetic patterns. These discs rotate so that heads, electromagnetic read/write devices, can either record data onto the platters or read what the platters already contain. Each platter has tracks which is then broken down into sectors which is where pieces of data is actually recorded.
What is meant by hard disk drive form factor?
A hard disk drive is a data storage device used for storing and retrieving digital information using rapidly rotating discs coated with magnetic material.

How magnetism is used to record sound and images in computers?
magnetism is the primary tech behind a few computer components 1. CRT monitor After the particle is ejected from the electron guy, its path is diverted through the electromagnetic field until it hits the right coloured spot on the aperture mask/grill. 2. Storage media a. Hard disk drives (not SSDs) For the last 40 years the metal platters within HDDs are coated with ferro magnetic material that can be written and read with an electromagnet solenoid b. Floppies, Diskettes, Zips, Tapes. The same idea as above except most of the media are removable, light and sensitive to wear and tear. Since the magnetic material is coated onto flexible plastic platters (or tapes). 3. Audio Speakers The main component within a speaker is the magnet and the cone. Supply the speaker with an audio signal and it should reproduce the sound. 4. Microphone - I guess it should be. but i dont know what its made of. 5. You mentioned sound and images. Images and video are stored as data on storage media. No. Magnetism is not a tech used in a webcam..
How does data get stored in hard disk and CD and what is the role of magnetism in the storage process?
HDDs record data by magnetizing ferromagnetic material directionally, to represent either a 0 or a 1 binary digit. They read the data back by detecting the magnetization of the material. A typical HDD design consists of a spindle which holds one or more flat circular disks called platters, onto which the data is recorded. The platters are made from a non-magnetic material, usually aluminum alloy or glass, and are coated with a thin layer of magnetic material. Older disks used iron(III) oxide as the magnetic material, but current disks use a cobalt-based alloy. The platters are spun at very high speeds (details follow). Information is written to a platter as it rotates past devices called read-and-write heads that operate very close (tens of nanometers in new drives) over the magnetic surface. The read-and-write head is used to detect and modify the magnetization of the material immediately under it. There is one head for each magnetic platter surface on the spindle, mounted on a common arm. An actuator arm (or access arm) moves the heads on an arc (roughly radially) across the platters as they spin, allowing each head to access almost the entire surface of the platter as it spins. The arm is moved using a voice coil actuator or (in older designs) a stepper motor. Stepper motors were outside the head-disk chamber, and preceded voice-coil drives. The latter, for a while, had a structure similar to that of a loudspeaker; the coil and heads moved in a straight line, along a radius of the platters. The present-day structure differs in several respects from that of the earlier voice-coil drives, but the same interaction between the coil and magnetic field still applies, and the term is still used.

What is a computer hardrive?
A harddrive is a device that stores data which can be retrieved later by an operating system. A harddrive is commonly made with stacks of platters on which data is stored maganetically and is read by the read head (little devices that move around the platters connected by an armiture)
