<?php
$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        

$categoryFactory = $objectManager->get('\Magento\Catalog\Model\CategoryFactory');$categoryHelper = $objectManager->get('\Magento\Catalog\Helper\Category');$categoryRepository = $objectManager->get('\Magento\Catalog\Model\CategoryRepository');$store = $objectManager->get('Magento\Store\Model\StoreManagerInterface')->getStore();$categoryId = 47; // YOUR CURRENT CATEGORY ID$category = $categoryFactory->create()->load($categoryId);$categoryProducts = $category->getProductCollection()
                             ->addAttributeToSelect('*');

foreach ($categoryProducts as $product) 
{    $imageUrl = $store->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA) . 'catalog/product' . $product->getImage();
    ?>

     <div class="product-container">                  <a href="<?= $product->getProductUrl(); ?>">

                     <div class="new-arrivals-image"><img src="<?= $imageUrl;?>"></div>
                     <div class="product-name"><span class="name"><?= $product->getName(); ?></span></div>
                  </a>
                  <div class="price"><span class="pt"><?= $product->getPrice(); ?></span></div>
               </div>

<?php}
?>

YOU CAN CALL YOUR CURRENT ID IN $categoryId VARIABLE. HOPE IT WILL WORK FOR YOU.
