Definition &amp; Working Explained<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>A <strong>magnetic stirrer<\/strong> is a compact lab instrument designed to mix liquids automatically. It works by creating a rotating magnetic field that spins a stir bar placed in the solution, which ensures uniform and quiet mixing without any direct contact with the sample.<\/p>\r\n\r\n\r\n\r\n<p>It comes in various variants:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Analogue models<\/strong> &#8211; simple and straightforward to use.<\/li>\r\n\r\n\r\n\r\n<li><strong>Digital models\u2014precise<\/strong>\u00a0speed\/temperature control with advanced features.<\/li>\r\n\r\n\r\n\r\n<li><strong>Magnetic stirrer with hot plate<\/strong> \u2013 allows heating and stirring simultaneously, offering greater flexibility in experiments.<\/li>\r\n<\/ul>\r\n\r\n\r\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\" \/>\r\n\r\n\r\n<h3 class=\"wp-block-heading\"><strong>Principle of Magnetic Stirrers\u00a0<\/strong><\/h3>\r\n\r\n\r\n\r\n<p>A stirrer works on the principle of magnetic coupling. When the device is switched on, a <strong><a href=\"https:\/\/en.wikipedia.org\/wiki\/Rotating_magnetic_field\" target=\"_blank\" rel=\"noopener\">rotating magnetic field<\/a><\/strong> is produced by magnets\/electromagnets located beneath the plate. This field interacts with the magnetic stir bar immersed in the solution, which causes it to rotate and mix the liquid efficiently.
