When Trump signed an executive order, he said that withdrawing from the TPP is a "good thing" for American workers.
In addition, Trump also signed a memorandum today, except for the military, other federal governments have frozen recruitment and abolished the Obama medical insurance law. Affected by this news, the US stock market vane: the Dow's decline once expanded to 90 points, a decline of more than 0.4%. 
According to Bloomberg's informed sources, Trump is also preparing to renegotiate the North American Free Trade Agreement (NAFTA), a free trade agreement between the United States and Canada and Mexico. Trump said on Sunday that he will meet with Canadian Prime Minister Trudeau and Mexican President Nieto to discuss the Nafta issue. He has always believed that this agreement has led to the loss of jobs in the United States.
TPP is an agreement reached by 12 countries to achieve trade liberalization between the United States and Japan, Mexico, Singapore and other Pacific Rim countries. This is an iconic component of former President Obama’s “Return to Asia†strategy. In the campaign, Trump declared that he opposed trade agreements such as TPP and Nafta.
In a video released last November, Trump promised to withdraw from the TPP on the first day of his appointment. He pointed out that this trade agreement "may be a disaster for our country."
Ring magnets are most commonly used in science experiments, although they also have medical applications. Some people have implantable cardioverter-defibrillators, or ICDs, that automatically apply shocks to their hearts if the rhythm develops irregularities. If the devices malfunction, they can shock the patients unnecessarily, leading to irregular rhythms and possibly death. Medical personnel sometimes place these magnets on patients` chests over the ICDs to disable the devices.
Ring magnets are similar to discs, but feature a hole in the centre. The reduced volume of the magnet results in less strength, but increases their versatility - rings slide easily onto tubes or rods. Rare Earth rings are available in sizes from 6mm outer diameter up to 120mm, and with a variety of internal diameters and thicknesses.
