Students will learn about gravity and magnetism as well as magnetic and non-magnetic influences. Students will also explore the relationship between magnetism and electricity. Challenge students to identify which non-contact force is at play and why the magnet acts the way it does.   <\/p>\n<p>Electricians must be aware of non-contact forces for many reasons. Electricians use aluminum conduits to run wires. When a magnet moves through a conductive, non-magnetic metal tube or pipe (like copper or aluminum), an electrical current is produced. In simple terms, this is Faraday&#8217;s law in action. When the magnet moves through a conductive, non-magnetic metal pipe, it descends due to gravity but at a slower rate due to the electrical current acting in the opposite direction of gravity. In simple terms, this is Lenz\u2019s law in action.     <\/p>\n<p>Some real-world applications that utilize Lenz\u2019s Law include electromagnetic brakes, induction cooktops, electric generators, Eddy Current balances and brakes, metal detectors, braking system on trains, levitating trains (Maglev trains), card readers, microphones, motors, inductors, and transformers. Electricians deal with many of these applications. <\/p>\n<p>Both electricians and pipe trade technicians work with various types of pipe. Aluminum pipe is used by electricians because it\u2019s lightweight and resists corrosion. Copper pipe is used by plumbers in commercial and industrial plumbing because it\u2019s a strong, tried and tested material. ABS pipe is used by plumbers in draining, waste, and venting applications. ABS is cheaper than copper and is faster and easier to install.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=&#8221;1\/3&#8243;][vc_column_text]<strong>L&#8217;heure<\/strong><\/p>\n<p>20\u201350 minutes<\/p>\n<p><strong>Mat\u00e9riaux<\/strong><\/p>\n<ul>\n<li>1 magnet<\/li>\n<li>3 aluminum pipes<\/li>\n<li>2 copper pipes<\/li>\n<li>1 ABS pipe<\/li>\n<li>1 steel pipe<\/li>\n<li>1 roll of electrical tape<\/li>\n<li>1 stopwatch<\/li>\n<\/ul>\n<p>[\/vc_column_text]<div class=\" ubtn-ctn-left \"><a class=\"ubtn-link ult-adjust-bottom-margin ubtn-left ubtn-normal \" href=\"https:\/\/learninginnovation.ca\/wp-content\/uploads\/2026\/03\/FR-Non-Contact-Force-Data-Sheet.pdf\" ><button type=\"button\" id=\"ubtn-2076\"  class=\"ubtn ult-adjust-bottom-margin ult-responsive ubtn-normal ubtn-no-hover-bg  none  ubtn-left   tooltip-6aeb3a0ce2b1c\"  data-hover=\"\" data-border-color=\"\" data-bg=\"#739600\" data-hover-bg=\"\" data-border-hover=\"\" data-shadow-hover=\"\" data-shadow-click=\"none\" data-shadow=\"\" data-shd-shadow=\"\"  data-ultimate-target='#ubtn-2076'  data-responsive-json-new='{\"font-size\":\"\",\"line-height\":\"\"}'  style=\"font-weight:normal;border:none;background: #739600;color: #FFFFFF;\"><span class=\"ubtn-hover\" style=\"background-color:\"><\/span><span class=\"ubtn-data ubtn-text \" >T\u00e9l\u00e9chargez une version PDF de cette fiche activit\u00e9<\/span><\/button><\/a><\/div>[\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner][vc_empty_space height=&#8221;45px&#8221;][vc_separator][vc_empty_space height=&#8221;45px&#8221;][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner]<div id=\"ultimate-heading-26966aeb3a0ce2b8a\" class=\"uvc-heading ult-adjust-bottom-margin ultimate-heading-26966aeb3a0ce2b8a uvc-2497 \" data-hspacer=\"no_spacer\"  data-halign=\"left\" style=\"text-align:left\"><div class=\"uvc-heading-spacer no_spacer\" style=\"top\"><\/div><div class=\"uvc-main-heading ult-responsive\"  data-ultimate-target='.uvc-heading.ultimate-heading-26966aeb3a0ce2b8a h2'  data-responsive-json-new='{\"font-size\":\"\",\"line-height\":\"\"}' ><h2 style=\"font-weight:normal;\">Proc\u00e9dure<\/h2><\/div><\/div>[vc_column_text]<\/p>\n<h3><span style=\"color: #7a9900;\"> Preparation <\/span><\/h3>\n<p>Lay materials out on a table or desk to ensure all materials are accounted for.

Explain that when a magnet is dropped in a steel tube, it\u2019s affected by both magnetism and gravity. However, because the magnetic force is stronger than the force of gravity, the magnet sticks to the pipe.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1710044671641{background-color: #f5f5f5 !important;}&#8221;]<strong>     <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-19673\" src=\"https:\/\/i0.wp.com\/learninginnovation.ca\/wp-content\/uploads\/2024\/02\/Grade-6-Science-3.png?resize=40%2C72&#038;ssl=1\" alt=\"\" width=\"40\" height=\"72\"><\/strong><strong>    <\/strong><\/p>\n<p>Ask students what will happen if they drop the magnet through the narrow 2-foot copper pipe.

Note that the magnet will move through the aluminum pipe at a slower rate than it did during the free fall and through the ABS pipe, but that it will fall at about the same rate as it did through the copper pipe and will not stick to the side of the pipe like it did in the copper pipe. Why is this? Discuss magnetic and non-magnetic materials. Point out in as much detail as desired that the magnet slows down in the non-magnetic metal pipes due to an induced electrical current acting in the opposite direction of the falling magnet as the magnet moves down the copper and aluminum pipes. This is known as Lenz\u2019s law.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;.vc_custom_1710044706411{background-color: #f5f5f5 !important;}&#8221;]<strong>     <\/strong><strong><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-20463\" src=\"https:\/\/i0.wp.com\/learninginnovation.ca\/wp-content\/uploads\/2023\/08\/Learning-objective.png?resize=40%2C72&#038;ssl=1\" alt=\"\" width=\"40\" height=\"72\">  <\/strong><\/p>\n<p>These pipes fit inside one another.
